SANGHA
Sangha
The Buddha’s dispensation is founded upon three guiding
  ideals, they are the objects of veneration: the Buddha,
  the Dhamma and the Sangha. The Buddha is the Teacher;
  the Dhamma is the Teaching; and the Sangha is the
  community of those who have realized the teaching and
  embody it in their lives. These three are together called
  the Three Jewels or Triple Gem. They are called the
  Three Jewels because for one who is seeking the way to
  liberation, they are the most precious things in the World.
The word ‘Sangha’ means those who are joined together,
  thus a community. However, "Sangha" does not refer to
  the entire Buddhist community. It does not mean the
  totality of Buddhists or of those committed to the
  Buddhist Path.
Sangha
The word, ‘Sangha’ signifies a smaller community within
   the larger Buddhist society. It refers in particular to the
   two such communities making for two kinds of sangha:
1. The Noble Sangha (Ariya Sangha) - the community of
     the noble ones or of Buddha’s true disciples.
2. The conventional Sangha - the order of fully ordained
     monks and nuns.
In principle, the conventional Sangha includes bhikkhunis -
   that is, fully ordained nuns - but in Theravada countries
   the full ordination lineage for women has become
   defunct, though there continue to exist independent
   orders of nuns.
Ariyan Sangha
The Ariyan Sangha is the community of noble persons, all
  those who have reached the supramundane paths and
  fruits. This Sangha consists of eight types of individuals
  joined together into four pairs. The four pairs are:-
1. The person on the path of stream entry and the stream
    enterer
2. The person on the path of once returner and the once
    returner.
3. The person on the path of non-returner and the non-
    returner.
4. The person on the path of arahatship and the arahant.
Ariyan Sangha
What unites all these persons and makes them a community
 is that they all share a penetration through direct
 experience of the innermost essence of the Dhamma. All
 these persons have followed the Buddha’s path to the
 height of wisdom and seen for themselves the ultimate
 truth, the truth of the unconditioned. The experience that
 makes a person an ariyan disciple is called the arising of
 the eye of Dhamma. We all have physical eyes by which
 we can see form. We also have mental eyes through
 which we can understand ideas intellectually, but what
 the Ariyan person has that an ordinary person lacks is
 the dhammachakkhu, the eye of truth, the penetrating
 vision that sees into the real nature of things, the vision
 that sees the unconditioned element, Nibbana.
Ariyan Sangha
By arousing the eye of Dhamma, the noble person has cut
  off the first three fetters, fetters of personality view,
  doubt and clinging to rites and rituals. Such a person
  (now an ariyan disciple) gains absolute confidence in the
  Triple Gem, in the Buddha, the Dhamma, and the
  Sangha. He can never go for refuge to any other
  teacher other than the Buddha, or take as his guiding
  principle any teaching other than the Dhamma. He has
  been spiritually reborn, born with a noble birth.
Ariyan Sangha
It is the profound experience of the Dhamma that makes a
    person a member of the Ariyan Sangha, a true disciple
    of Buddha.
The status of an Ariyan Sangha is not established by any
    formal act of ordination. Any person - monk or nun,
    layman or laywoman - who penetrates the Dhamma, who
    arouses the eye of the Dhamma, immediately becomes
    an Ariyan disciple of the Buddha. Lay persons living at
    home can also reach all four levels of liberation. But the
    lay people who have become Arhants are very few and
    when they do so, according to natural law they
    immediately renounce the household life and enter the
    monastic order.
Ariyan Sangha
Those who become ariyans have entered the definite path
  to final liberation. They have stepped beyond the ranks
  of the multitude caught up in craving and ignorance
  revolving in birth and death. They can never fall back to
  the level of a worldling because they have realized the
  truth by direct experience. They are now bound to reach
  full enlightenment and final liberation.
Ariyan Sangha
The highest of the noble disciples is the arhant. He is the
  one who never comes back to any form of existence high
  or low. He has reached enlightenment right in his body,
  he has cut off all craving and extinguished all
  defilements. He lives out his days in the bliss of liberation
  until the break up of the body. With the break up of the
  body, he attains the final goal, the Nibbana element
  without residue.
The Ariyan sangha is the jewel of the sangha. It is this
  sangha that functions as one of the three refuges.
Ariyan Sangha
When Buddhists recite "Sangham saranam gachchâmi" (I
 go for refuge to the Sangha), they are referring to the
 Ariyan Sangha. The Ariyan Sangha is absolutely
 essential to the Buddha’s dispensation, for the ariyan
 disciples stand as living proof of the truth of the
 Buddha’s teaching. The Ariyans are the ones who have
 put the teaching to the test, who have practised the path
 and verified the Dhamma in their own experience. They
 are the ones who have accomplished the aim of the
 Dhamma. The Buddha’s teaching aims at transforming
 ordinary people from worldlings into noble people, at
 bringing them to the stages of liberation.
Ariyan Sangha
They are the guides and models. They encourage us to
  follow the path, since they began as ordinary people like
  ourselves, but by practising the path they have risen up
  above the ordinary plane and reached the state of
  spiritual nobility. Through their own attainments they can
  give effective instructions to others, instructions that are
  not based on mere guesswork or book learning but on
  personal experience.
Conventional Sangha
The monastic order is called the conventional Sangha
  because admission to the order depends entirely on the
  convention of ordination, which can be given to any
  properly qualified candidate. It does not require any
  special spiritual attainment, but simply a person who
  wishes to enter the order and is free from any of the
  conditions that obstruct ordination.
The monastic order is not a jewel or a refuge in the highest
  sense. It is still a jewel in the secondary sense.
Conventional Sangha
The monastic Sangha is regarded as extremely precious,
  and worthy of deep reverence and respect for two basic
  reasons. Firstly because the members of the sangha
  continue to follow the holy life laid down by the Buddha
  in its fullness; and secondly because they transmit the
  teaching of the Buddha from generation to generation,
  out of concern for the welfare of others. They keep the
  Dhamma alive in the world.
The Buddha established the Sangha in order to provide
  ideal conditions for reaching the ariyan state, for
  attaining Nibbana.
Monastic Order
The bhikkhus who take ordination into the order are those
  who have followed the Buddha into the state of
  homelessness. They take on the Buddha’s mode of
  practice; they wear his robe; they live according to his
  rules. The Buddha laid down the brahmacariya, the holy
  life as the way to deliverance. The monastic state
  provides the optimal conditions possible in this world for
  living the holy life intended by the Buddha.
Ariyans do not arise only from the monastic sangha. Those
  persons who have become monks and nuns have the best
  opportunities for practicing to reach the ariyan states.
 Monastic Order
The second reason that the monastic order is revered so highly
  as mentioned before is that the members have the function
  to transmit the Buddha’s dispensation.
They keep alive the way of life and practice established by
  the Buddha. They show to others it’s possible to live a life
  of purity, of renunciation, of restraint, meditation and
  realisation.
By training disciples, they ensure that the Buddha’s
  dispensation is passed on from one generation to another
  so that it doesn’t disappear from this world.
By studying the scriptures and teaching them, they preserve
  the teachings of the Buddha, spread and propagated for
  the welfare of others.
For these reasons, the monastic order stands as a field of
  merit, worthy of respect, offerings and support.
Formation and Growth of the Sangha
The formation of the Sangha took place soon after the
   Buddha finished his first discourse, to the five ascetics.
   When the Buddha finished explaining the Four Noble Truths
   and the Noble Eightfold Path, Kondanna attained the stage
   of stream entry and requested to be a disciple of Buddha.
The Buddha ordained him, ‘Come bhikkhu, the Dhamma is well
   proclaimed. Live the holy life for the complete ending of
   sufferings.’ With these words, Kondanna became the first
   bhikkhu, a monk disciple of Buddha.
In formal term, a sangha is a community of a minimum of four
   monks.
Formation and Growth of the Sangha
 Then the Buddha continued his discourse, and the other four
   ascetics gained stream entry after his talk. They also
   asked to become bhikkhus under the Buddha. They were
   ordained bhkkhus with the same words. They were
   ordained with the same words. The Sangha was formed
   for the first time, a community of five monks headed by
   the Buddha.
 Shortly after that, the Buddha then taught them the Truth of
   Anatta (egolessness). At the end of this discourse, the five
   monks achieved enlightenment, destroyed all defilements
   and became arahats, fully liberated in mind.
Formation and Growth of the Sangha
In the months and years ahead, the sangha continued to
   expand very rapidly for several reasons. The age when
   the Buddha lived was a period when spiritual ideal was
   highly valued. The prevalent religions of Buddha’s time
   failed to meet the spiritual needs of the people. In
   contrast to the other teachings of the time, the Buddha
   offered a clear and direct path to the highest goal, a
   path that is open to personal verification, appealing in
   simplicity and practicality. The Buddha’s teachings
   attracted followers who wanted to live the monastic life.
   They came from all castes and social classes, kings, princes,
   aristocrats, merchants, outcasts, beggars, etc. By the time
   the Buddha passed away, the order grew to thousands in
   numbers, spread out in northern India.
Renunciation and Deliverance
The key move that characterizes the act of becoming a
  monk is renunciation. The initial act is pabbajja, going
  forth from the household life into homelessness.
While the Buddha’s teaching is applicable to those living
  the household life, anyone who has correctly grasped the
  drift of the Buddha Dhamma will see that the path of
  renunciation follows from it with complete naturalness.
The Buddha teaches that life in the world is inseparably
  connected with dukkha, with suffering and
  unsatisfactoriness, leading us again and again into the
  round of birth and death.
Renunciation and Deliverance
The reason we remain bound to the wheel of becoming is
  because of our attachment to it. We hang on to it through
  our craving for desire, for power, for continued existence.
  To gain release from the round, we have to extinguish our
  craving. That is the highest renunciation, the ultimate inner
  act of renunciation. But to win that attainment we
  generally must begin with relatively easy acts of
  renunciation, and as these gather force they eventually
  lead us to a point where we no longer are attracted to the
  lures of secular life. When this happens, we become ready
  to leave behind the household life, to enter upon homeless
  state in order to devote ourselves fully to the task of
  removing the inner subtle clinging of the mind.
Renunciation and Deliverance
The homeless life is not absolutely essential for this work.
  True renunciation is an inner act, not a mere outer one.
  But the homeless life provides the most suitable outer
  conditions for practising true renunciation.
The holy life requires purified conduct, but household life
  stimulates many desires that run contrary to pure
  conduct. The homeless life is a life of meditation, calling
  for constant mindfulness, clear awareness and
  contemplation. All this requires time, a calm
  environment, freedom from external pressures and
  responsibility. The Buddha founded the Sangha in order
  to provide such objective conditions.
Bhikkhu
The bhikkhu, the Buddhist monk, is not a priest; he does not
  function as an intermediary between the laity and any
  divine power, not even between the lay person and the
  Buddha. He does not administer sacraments, pronounce
  absolution or perform any ritual needed for salvation.
  The main task of a bhikkhu is to cultivate himself along
  the path laid down by the Buddha, the path of moral
  discipline, concentration, and wisdom.
Bhikkhu
Entrance into the Sangha is not binding for life time. One
   who becomes a Buddhist monk does not take life-long
   vows. In some Buddhist traditions in countries like Sri
   Lanka, it’s expected that those who take higher
   ordination remain in the robe for life.
If a person finds himself unsuitable for monastic life he is
   free at any time to leave the order and return to lay life
   without any kind of religious blame attached to him,
   without incurring any kind of obstruction to his spiritual
   progress.
In some countries like Burma and Thailand, it’s customary
   for all males at sometime in their life to take ordination
   for short periods.
Distinctive Marks of the Bhikkhu
The distinctive marks of the bhikkhu in all the Buddhist
  countries in most Buddhist traditions are the shaven head
  and the saffron robes. The reason the bhikkhu adopts this
  appearance is rooted in the very nature of his calling.
The Buddhist monk seeks to realize the truth of anatta, of
  selflessness. This means the relinquishing of one’s claims to
  stand out as a special individual, to be a "somebody".
  The aim of the bhikkhu is to eliminate the sense of ego,
  of self identification. Our clothes, hairstyle, and beard
  often become subtle ways by which we assert our sense
  of identity or express our self image. Bhikkhus give up
  their personal identity and blend into a larger body the
  Sangha.
 Distinctive Marks of the Bhikkhu
The robe and the shaven head is also the reminder and
  theme for their daily reflection. "My way of life is
  different from that of worldly people". Unlike the
  common people, he leads a life of restraints, self-control,
  and inner cultivation. The robe also serves to make others
  aware of the Buddha’s teaching. His conduct has the effect
  of impressing on others the fruits of the Buddha’s teaching.
Another special aspect of the lifestyle of the Buddhist monk is
  that he lives in dependence on the offerings of others. He
  does not work for his living, he does not receive payment
  for his religious services, but he lives entirely in
  dependence on the support of the laity. Those who have
  confidence in the Dhamma provide him with the basic
  requisites, his robes, food, dwelling place, medicines, and
  whatever other simple material support he might need.
Relationship Between Sangha and Lay People
The monks and nuns do not ask society for support. The code
   of monastic disciplines prohibit the monks and nuns from
   asking lay people for material goods except in the case of
   close relatives.
The monks and nuns who live in accordance with the Dhamma
   are a blessing for the lay people who provide them with
   the requisites. The benefits they provide can be found at
   several levels:
1. First, by receiving the support, they are able to become
   teachers of the Dhamma. Because they are freed from the
   necessities of providing for themselves economically, they
   can study the teaching, learn it thoroughly, and teach it to
   others. They guide and teach others the principles that lead
   to their spiritual welfare.
Relationship Between Sangha and Lay People
 2. At a deeper level, the monks and nuns who receive the
    support maintain the traditions of Buddhist practice,
    especially the higher practices of meditation. They serve
    as an example for others; as models of those who are
    pursuing the highest spiritual ideals. They show that the
    Dhamma is just not a set of abstract theories, but a real
    path that can be practised; and they inspire others to
    undertake the practice and lead them to liberation.
 3. A third benefit the sangha provides is to serve as a field
    of merits for others. The Buddha teaches that giving,
    dana, is a source of merit. The merit that comes from
    giving is proportional to the purity of the recipient.
Relationship Between Sangha and Lay People
 When the receivers are persons striving for enlightenment
   and liberation, the highest goals, they become the most
   fruitful field of merit. By making gifts to the sangha of
   the requisites, robes, food, etc, the lay people gain merit
   that will sustain them in their own quest for liberation,
   which will bring them benefits in this and future lives.
 Perhaps the primary symbolic expression of the close
   relationship between the lay people and the sangha is
   the alms round. The monks acquire their food by walking
   with eyes downcast, silently and mindfully; from house to
   house without discrimination, giving everyone the same
   opportunity to make merit, gathering the offerings in
   their alms bowls.
Relationship Between Sangha and Lay People
  The monk does not ask for anything. He is not a beggar.
    The bhikkhu shares the offerings with everyone in the
    monastery.
  The practice of going for alms round is a source of joy for
    everyone, the bhikkhu receives his material support; the
    lay people gain the chance to practice generosity and
    acquire merit.
SANGHA – PART II
Ordination and Precepts
There are two basic levels of monastic status in the sangha,
  the rank of the samanera and the rank of the bhikkhu.
  The samanera is a novice monk and a bhikkhu is a fully
  ordained monk. ‘Samanera’ means a little samana
  (sramana) or monk. A samanera is one who has left the
  household life and entered the monastic fold, but he has
  not yet been fully admitted to the sangha. He is still
  preparing for full ordination as a bhikkhu. He might have
  to undergo a training for a period of several months or
  years, but sometimes mature men are given the novice
  ordination and full monk ordination on the same day.
The ceremony of becoming a samanera is called pabbajja,
  the going forth from lay life to homeless life.
Ordination and Precepts - Samanera
To become a samanera, the candidate must be at least 7
  years old; physically fit; provided with robes; and
  accepted by a senior bhikkhu as a pupil. At the
  ceremony of ordination, the candidate approaches his
  preceptor with the head shaved and carrying his robes in
  his hand, he then requests his preceptor to be given the
  pabbajja. The preceptor would then give him an
  explanation of what is involved. The preceptor takes the
  robes and gives them back and this marks the
  acceptance of the candidate as a samanera. The new
  novice then goes off to the side, takes off his lay clothes
  and puts on the robes.
Ordination and Precepts - Samanera
He returns to the teacher and requests the teacher to give
  him the three refuges and the ten precepts of a
  samanera. The teacher will then recite the formula for
  the three refuges and the ten precepts, the samanera
  repeating them after the preceptor. From then on, the
  samanera must observe the ten basic precepts of the
  monastic life. These are:
1. To abstain from killing or taking life.
2. To abstain from taking what is not given or stealing.
3. To abstain from incelibacy, to lead a life of strict
    chastity.
4. To abstain from lying.
5. to abstain using from using intoxicants (drinks & drugs).
Ordination and Precepts - Samanera
6.  To abstain from eating (taking solid food) at the wrong
    time (from midday to next dawn).
7. To abstain from singing, dancing, musical instruments
    and unsuitable shows.
8. To abstain from using ornaments, scents, garlands and
    perfumes that beautify a person.
9. To abstain from using high or luxurious seat and bed.
10. To abstain from accepting gold or silver or money.
During the period of training, the young novice monk must
    study the Dhamma, learn the aspect of monastic
    discipline and prepare himself for future full ordination.
Ordination and Precepts - Bhikkhu
The ceremony of full ordination as a bhikkhu is called
  upasampada. To be eligible for upasampada, the
  candidate must have been a samanera for sometime;
  twenty years old; free from impediments such as incurable
  diseases (leprosy, tuberculosis and epilepsy); a free man,
  not in debt, not in debt, exempt from military service; have
  permission from the parents. He must have a complete set
  of robes and an alms bowl when he comes for the
  ceremony, these are usually provided by a lay supporter.
The ceremony of upasampada requires a sangha of at least
  five bhkkhus, usually more are present. The sangha is
  headed by a bhikkhu of at least 10 years’ standing in the
  order, who has a good knowledge of Dhamma and
  Vinaya or code of moral discipline. This senior monk
Ordination and Precepts - Bhikkhu
  will serve as the preceptor for the new bhikkhu.
The ceremony begins with a monk chanting the motion that
  such and such a candidate requests upasampada with
  such and such a senior monk as his preceptor. Three
  announcements of this fact are made. If none of the
  bhkkhus present object, then when the third
  announcement is finished, the candidate is accepted as a
  bhikkhu.
After the actual ordination, the preceptor explains to the
  new bhikkhu the four things that are absolutely
  prohibited (parajika) for a newly ordained monk:
1. Engaging in sexual intercourse of any kind.
Ordination and Precepts - Bhikkhu
2.  Taking anything of value that is not given.
3. Killing another human being.
4. Falsely claiming to have reached some higher spiritual
    attainment.
If a bhikkhu commits any of the above forbidden acts, he
    is immediately expelled from the sangha; and he can
    never be ordained again in this life time.
The preceptor then explains the four supports of the
    homeless life. These are:
1. To live on food collected on alms round.
2. To use robes made from cast-off rags.
Ordination and Precepts - Bhikkhu
3. To live beneath a tree.
4. use cow’s urine as medicine.
These four observances are not compulsory. Monks are
   allowed to accept food offered by lay people at home
   or brought to the monastery. Monks can wear robes
   already prepared by householders. They can live in
   buildings like temples or monasteries or cottages. They
   can use any kind of proper medicine. Nowadays only
   the first support is commonly followed. However the
   formula is still recited as a formality to emphasise the
   spirit of poverty, simplicity and purity that are essential
   to a monk’s life.
Ordination and Precepts - Bhikkhu
The bhikkhu is allowed to own eight articles. These include:
•    three robes: antaravasika or under-robe worn around
    the waist; upper robe or utarasangha worn over the
    shoulder covering the upper part of the body; double
    thick outer robe, sanghati, usually worn only in cool
    weather.
•   Belt; alms bowl; razor and needle; and water strainer.
In actual practice, bhikkhus usually own a few other extra
    necessities, varying in quantities according to their life
    styles. Teaching bhikkhus in towns would need extra
    robes, books, note paper, pens, etc. Bhikkhus living in
    the forest would need little extra beyond their
    requisites, fan, sandals, clock, umbrella etc.
Ordination and Precepts - Bhikkhu
A monk has to obtain his requisites in a pure way. He
   doesn’t work at a profession. He is forbidden to beg,
   coerce or persuade others to give them. He receives the
   requisites through the generosity and kindness of the
   laity.
In using the four principle requisites, the robes, the alms
   food, the shelter, and medicine, he has to reflect on their
   proper purposes.
When he puts on his robes, he has to reflect that he uses the
   robes for the purposes of keeping off the cold, the heat,
   the sun, wind and creeping things and for covering up the
   body.
Ordination and Precepts - Bhikkhu
He reflects that he uses the alms food in order to support
   his life, to keep himself in good health, to prevent
   disease and to live the life of holiness.
He reflects that he uses the shelter to keep out the heat,
   cold, mosquitoes, gnats, and to protect himself from the
   weather.
He reflects that he uses the medicines for the purpose of
   keeping off disease, for the maximum of health and
   wellbeing.
Life in the sangha is regulated by a body of rules called
   the Vinaya. The word, ‘Vinaya’ means ‘leading away’,
   the code of rules that lead us away from wrong deeds
   of body and speech.
 Vinaya
 Vinaya is contained in the Vinaya Pitaka, the Books of
  Discipline. These books set forth the precepts of monastic
  life. Some of these precepts are moral in nature and
  concerned with the fundamentals of spiritual development.
  Others are principles of etiquette, which help to establish
  harmony among the monks themselves, and between the
  sangha and laity as a whole.
The heart of the vinaya is the code of 227 rules called the
  patimokkha. These are the backbone of monastic discipline.
  The rules of the patimokkha are classified into several
  categories of different degrees of moral weight. The most
  important are the four parajika, four prohibited acts -
Vinaya
 sexual intercourse, theft, killing another human being, and
   false claim of spiritual attainment. Violation of any of
   these four leads to defeat, expulsion from the order.
Thirteen other rules of lesser degree of gravity if violated
   lead to a period of penance with temporary suspension
   of monastic privileges.
The remaining rules vary in importance and in the
   consequences that are entailed when violated. For good
   monks, it is important that they try to keep all the rules as
   scrupulously as they can.
All the rules might not seem to be extremely serious, but the
   problem is once a person starts breaking minor rules, it’s
Vinaya: Patimokkha
  often a matter of time until he starts breaking major
  rules. Therefore the guiding principle for a monk who is
  serious in following the Buddha’s path is to try to
  maintain and protect all the rules to the best of his
  ability. The foundation of higher stages of spiritual
  training is moral discipline. For a bhikkhu, the backbone
  of his moral discipline is the patimokkha.
The patimokkha is recited by the sangha together at a
  ceremony called ‘uposatha’ which is held on the day of
  the full moon and the new moon of each lunar month. It’s
  held in a monastery whenever there are four monks or
  more living together.
Uposatha; Vassa
Before the uposatha ceremony takes place, the bhikkhus
  need to confess their transgressions to one another. Then
  they all sit together, one senior bhikkhu will recite the
  patimokkha while the rest will listen. While it is recited, if
  a monk remembers a transgression he has committed,
  then he will confess the transgression before the group as
  a whole.
Another special occasion of the monastic life is the vassa.
  Vassa is a period of three months coinciding with the
  rainy season of India, from the full moon day of July to
  the full moon day of October. During vassa, the monks
  take up residence in a single dwelling without travelling
  outside except in emergencies or special cases when their
  presence is required somewhere.
Vassa
The rule requiring the bhikkhu to observe the vassa was
  made by the Buddha because of the conditions in India
  during the time of the rain. When the rain fell, the earth
  would teem with vegetation and insect life would become
  abundant. If the monks travelled a lot, they would
  trample on the crops, ruined the people’s field and
  destroy insect life. To prevent this, the Buddha made the
  rule for the monks to stay in a fixed abode for a period
  of three months. During this time the lay people would
  provide them with their requisites and take care of the
  monks with great felicity. Even now in places where there
  is no rain during this period, it’s traditional for the monks
  to observe the retreat of vassa.
Vassa
During this period the bhikkhus would devote themselves to
  study, or meditate or write to perfect their own skills.
At the close of the vassa, the bhikkhus would assemble and
  hold a ceremony called ‘pavarana’. At the pavarana
  ceremony, each monk invites the other monks in the
  community to point out any wrong he might have
  committed and to ask for their patience and forgiveness
  for any wrongs he might have committed. When the
  pavarana is finished, the vassa is completed.
Usually within a month after the end of the vassa, a major
  ceremony called kathina takes place, bringing together
  the laity and the sangha, symbolising the unity of the
  Buddha’s followers.
Vinaya
At the kathina ceremony, the laity offer new robes to the
  monks who have observed the vassa retreat. They also
  bring other goods needed by the temple of monastery.
All the monks, irrespective of their age and standing, are
  guided by the same training in moral discipline
  concentration and wisdom. All share the same
  disciplinary code, the patimokkha, and the rest of the
  vinaya.
Beyond these, the members of the order divide into two
  basic types, the career of books (study of scripture) and
  the career of practice (meditation). These two are not
  absolutely exclusive. Ideally there should be a synthesis
  of the two.
Careers: Pariyatti & Patipatti
Monks who study scriptures would do daily meditation
 while the monks who meditate would have some
 proficiency in the scriptures. Generally there is a
 tendency towards specialisation. Some monks emphasise
 the pariyatti Dhamma (study of scriptures); others
 emphasise patipatti Dhamma (practice meditation).
 Monks following the two careers usually live in different
 regions. Monks who follow the career of study usually
 live in the cities, towns or villages, while the following the
 way of strict practice usually live in more remote areas in
 the forests. This division is not so sharp. Sometimes in city
 monasteries, there are monks who are devoted fully to
 meditation. In some forest monasteries, there are also
 monks who are specialists in scriptures
Pariyatti
The main task of the monks following the career of books is
  to study, teach and expound the scriptures of Buddhism.
  In the Theravada tradition, the main scriptural authority is
  the Tripitaka, the three baskets of doctrine, set down in
  the ancient Pali language. These are the Sutta Pitaka
  (discourses of the Buddha and the great disciples),
  Vinaya Pitaka (the Books of Monastic Disciplines), and
  the Abhidhamma Pitaka (philosophical and psychological
  treatises). To learn means to memorise. Memorisation is
  still emphasised today. Monks would memorise the
  scripture and study the commentaries to learn the
  meaning thoroughly. When they have gained some
  proficiency, they would teach others, give sermons and
  lectures, and train younger monks in the scriptures.
Town Bhikkhus
Those studying bhkkhus who live in the vicinity of cities,
  towns or villages participate in various religious rites in
  domestic life of the laity. They interact with the laity in all
  occasions in daily life from birth to death. Their main
  involvement are in meal invitation and chanting of sutta
  and preaching. Dana is a great source of merits for the
  lay people. Dana would be offered to the monks by a
  family or group of lay people. After the meal, the monk
  would give a sermon followed by chanting of
  benediction.
Special chanting sessions are also held from time to time. A
  group of monks would be invited to chant special
  protective discourses, the paritta.
Town Bhikkhus
At periodic intervals, monks would deliver lengthy sermons.
  These can be attended by large numbers of lay people
  who make these occasions of preachings their main
  opportunities for learning the Dhamma.
On special occasions in Uposatha day, devoted lay people
  would go to the temple and stay the whole day and
  night. On these occasions, they would take the eight
  precepts living like novice monks and nuns. They devote
  their time to meditation, reciting texts and to asking
  monks questions, quiet study and listening to several
  lengthy discourses which might be delivered during the
  uposatha period.
Forest Bhikkhus
In contrast to the life of the town bhikkhus, the life of the
   forest bhikkhus is quiet. Their time is reserved for inner
   work, for cultivating their mind for the development of
   calm and insight. In forest hermitages, the group of
   monks live together usually under the guidance of an
   accomplished meditation master. They live in small huts
   usually separated at some good distance from one
   another to give the seclusion needed for the practice.
The training of the forest monk follows the ancient pattern
   coming down from the time of Buddha – sila, samadhi
   and panna. He lives a life of discipline; contentment with
   simplicity; applies control of the senses; mindfulness in
   daily actions and activities; meditation to purify the mind
   and develop jhana as a base to develop wisdom.
Place of Nuns in Buddhism
In India at the time Buddhism arose, women were held in a
   subservient position, made to be dependent on men in all
   periods of their life – dependent on the father in their
   childhood, dependent on the husband in their maturity,
   dependent on the sons in their old age. They were bound
   down by domestic duties and burden. They received
   little consideration as individuals in their own right. Their
   capacity for spiritual development went unrecognised.
   It’s against this background that we should view the
   Buddha’s move in creating the bhikkhuni sangha, an
   order of fully ordained nuns.
The Buddha hesitated to permit women to enter the
   homeless life. When he agreed to do so, he laid down
   several special regulations for the nuns.
 Bhikkhuni Order
The order of nuns was established in the early years of the
  Buddha’s ministry. One year after his enlightenment , he
  returned to his homeland of Kapilavatthu and taught
  Dhamma to his people, the Sakyans. A good number of
  them, men and women achieved insight and attained
  different levels of realisations. His foster mother,
  Mahapajapati Gotami became a stream-enterer and his
  father, the King became a non-returner. Several years later,
  he returned to Kapilavatthu to see his father who was lying
  in his death bed. He taught Dhamma to his father. His
  father attained arahatship just before dying.
After his father’s death, his mother Mahapajapati went to the
  Buddha and asked him if women could be allowed to enter
  into the homeless life. The Buddha did not refuse flatly.
Bhikkhuni Order
The Buddha discouraged her, ‘please do not ask for women
  to be allowed to go forth into the homeless life.’ He
  repeated this three times. Probably he was thinking that
  the homeless life which was difficult even for men to
  follow would be much harder for the women who had
  been brought up in sheltered life in the palace to follow.
The Buddha left Kapilavatthu for Vesali, about 250-300
  miles away. Meanwhile Mahapajapati cut off her hair
  and put on saffron robe. Together with a group of
  Sakyan women, she set out for Vesali. When she arrived
  in Vesali, Venerable Ananda saw her standing there, her
  feet were swollen and her limbs were covered with dust,
  looking very unhappy with tears on her face. Venerable
  Ananda asked her why she was standing there like that.
Bhikkhuni Order
She explained to Venerable Ananda that the Buddha
  would not allow the women to go forth. Then Venerable
  Ananda approached the Buddha and on behalf of the
  women asked the Buddha for permission for the women
  to go forth into the homeless life. He asked three times.
  Three times, the Buddha did not refuse but responded,
  ‘do not ask for women to be allowed to receive the
  going forth.’ After the third time, Venerable Ananda used
  a different tactic, he asked, ‘Venerable Sir, is it possible
  for women to achieve the path and fruit? Is it possible for
  them to achieve arahatship?’. The Buddha said, ‘it’s
  possible, Ananda’.
Bhikkhuni Order
Then Venerable Ananda said, 'If this is so, and since
  Mahapajapati had been so helpful to you, when your
  mother died, she became your foster mother and gave
  you milk and took care of you in every way, for this
  reason, it would be good if women could obtain the
  going forth.’ Then the Buddha said he would allow the
  women to go forth to become bhikkhuni if they would
  agree to eight principles.
These eight principles all have the effect of making the
  bhikkhuni sangha to some extent subordinate to the
  bhikkhu order. They require the order of nuns to show
  special respect and reverence for the bhikkhus.
Bhikkhuni Order
These rules were intended to reduce the contact of the nuns
  and monks that may lead to corruption of the order, and
  to retain the respect of the laity for the order and the
  Dhamma so that the Dhamma would not disappear due
  to possible loss of respect from the laity.
Once the order of bhikkhuni was formed, it attracted
  women from all walks of life. Women of royal staff,
  poor women ordinary housewives, courtesans, young
  girls, etc left their homes to put on the yellow robes of
  Buddhist nuns. Some achieved arahatship; some became
  prominent members of the sangha, masters of meditation,
  excelling in wisdom and concentration, in learning and
  supernormal powers.
Bhikkhuni Order
Some of the nuns’ discourses are collected in the Sutta
   pitaka. The verses of the nuns who had achieved
   arahatship were collected together into a single book of
   the Sutta Pitaka, the Therigatha, the Verses of the Elder
   Nuns.
Like the order of the bhikkhus, the order of nuns has its own
   patimokkha. These contain more than 300 rules, more
   than that of the order of monks. One of the regulations
   for the bhikkhuni sangha which was to have unfortunate
   consequences was the requirement that a woman novice
   has to receive full ordination from both orders, the order
   of monks and the order of nuns.
Bhikkhuni Sangha
For several centuries, the bhikkhuni sangha continued to
  flourish in India. During the 3rd century B.C., King Ashoka
  allowed his own daughter, Sanghamitta to become a
  bhikkhuni. Together with a group of nuns, Sanghamitta
  travelled to Sri Lanka with a branch of the Bodhi tree
  and helped to establish the bhikkhuni sangha in Sri
  Lanka. After Sanghamitta had set up the bhikkhuni
  sangha, many women from all the different strata of the
  Singhalese society joined the women’s order which
  became famous for the saintliness and piety of its nuns.
  The bhikkhuni order continued to thrive in Sri Lanka for
  many centuries, right up to the 10th century A.D.
  Bhikkhuni Sangha
During this period, it received the support of the kings, royal
  governments and laity. Due to a series of invasions from
  south India, the bhikkhuni sangha seemed to die out in the
  10th century A.D. The bhikkhuni order also disappeared in
  India.
Since ordination as a bhikkhuni has to be received from an
  existing bhikkhuni sangha, when the latter has died out,
  ordination becomes impossible and the lineage cannot
  continue.
Today, women in Theravada countries continue to be drawn to
  the monastic life, living the holy life of ancient bhikkhunis;
  serving as teachers and meditation master; engage in social
  services. (see separate article by Bhikkhu Bodhi for more
  current development of Theravada nuns)
