Indian Philosophy:
Religion: Physical and applicable in life
Philosophy: Meta physical (it questions religion)
4 elements of Indian philosophy:
          Soul: migrates from one form to another based on Karma; imperishable
          Karma: Conduct / behaviour
          Rebirth: transmigration of soul into another body
          Moksha: Freedom from the cycle of birth and death
                  o     Atma merges with Paramatma (Supreme Soul) upon
                        attainment of Moksha
                  o     Buddhism and Jainism talk about Nirvana (self becomes
                        the supreme soul)
No concept of Heaven or Hell in Upanishads. Heaven mentioned for the 1st time
in Ashoka literature.
Orthodox Philosophy:
Shada-Darshana: Divided into six āstika (orthodox) schools of thought, or
darśanam, which accept the Vedas as supreme revealed scriptures.
6 Pramanas to attain knowledge:
          Pratyaksha — perception
          Anumana — inference
          Shabda — testimony of reliable sources
          Upamana — comparison and analogy
          Arthāpatti — postulation, derivation from circumstances
          Anupalabdi — non-perception, negative/cognitive proof
The āstika schools are:
1. Samkhya: Kapil Muni (wrote Samkhyasutra)
         o   Rationalist school
         o   An Atheistic and strongly dualist theoretical exposition of
             consciousness and matter.
         o   NO GOD, KARMA YES
         o   Soul and Matter are different entities
         o   Jiva: Purusha bounded to prakriti in some living form
         o   Moksha can be achieved through knowledge.
                          K/W can be acquired through 3 main
                           concepts: Pratyaksha, Anumana and Shabda
         o   Original View: Materialistic School of Philosophy
                          Divine agency not needed to create universe
                          Propounded rationalist and scientific view of
                           creation of universe
                          World owed its existence to Prakriti (matter)
         o   New View: Spiritual School of Philosophy
                          Along with nature, Purusha (consciousness) was
                           necessary to create universe
                          Spiritual view of the creation of universe
                          Coming together of nature and spiritual elements
                           created world.
         o   It provided the materialistic ontology for Nyaya
             and Vaisheshik, but there is very little original
             literature in Samkhya.
2. Yoga: Patanjali (wrote Yogasutra)
         o   Yoga literally means union of 2 major entities
         o   Theistic as it accepts the principle of personal god
             although it doesn't require it.
         o   It also relies on Pratyaksha, Anumana and Sabda to gain
             knowledge
         o   A school emphasising on meditation, contemplation and
             liberation.
         o   Meditation and Physical application of yogic techniques
             (asanas and pranayamas) will lead to salvation (in addition
             to what is being done in Samkhya — gaining knowledge).
         o   Means of achieving freedom / mukti:
                          Yama: Self control
                          Niyama: Observation of rules
                          Pratyahara: Choosing an object
                          Dharna: Fixing the mind over the object
                          Dhyana: Concentrating on the object
                          Samadhi: Merging of the mind and object that
                           leads to the final dissolution of the self.
3. Nyaya (or logic): Gautam Rishi (wrote NyāyaSūtras)
         o    Realist school
         o    Explores sources of knowledge
         o    4 / 6 pramanas accepted — Pratyaksha, Anumana,
              Upamana, Sabda
         o    Believes in the technique of logical thinking to achieve
              salvation.
         o    Life, death and salvation are mysteries that can be solved
              through logical thinking.
                          Using tools like — inference, hearing and analogy
         o    Only “real knowledge” will lead to salvation.
4. Vaisheshika: Kanada Rishi
         o    Naturalist school
         o    It believes in the physicality of the universe
         o    Universe created by 5 main elements called Dravya: Air,
              Water, Earth, Fire and Ether (sky)
         o    Being an empiricist school it also created the theory
              of atomism.
         o    Theory that all knowledge is based on experience derived
              from the senses.
         o    It accepts only 2 methods to gain knowledge — Pratyaksha
              and Anumana
         o    They believed in God, Karma and Salvation — but it was
              like creation and destruction of Universe, a cycle under the
              control of God
5. Mimāṃsā:   Jaimini
         o    An anti-ascetic and anti-mysticist school of orthopraxy.
         o    Focuses on the analysis of Samhita and Brahmana portion
              of Vedas
         o    Mimamsa: Art of reasoning, interpretation and application
         o   Fulfil all the duties prescribed in the Vedas to achieve
             salvation. Rituals must be performed and with appropriate
             knowledge and reasoning . Only then salvation can be
             achieved.
         o   Depending on good and bad deeds committed, bliss of
             heaven can be enjoyed and the cycle continues. Only
             salvation can break this cycle.
         o   People took help from Brahmanas to perform the rituals
             which elevated the status of Brahmanas.
6. Vedanta: Badrayana (wrote Brahmasutra)
         o   The last segment of knowledge in the Vedas, or the 'Jnan'
             (knowledge) 'Kanda' (section).
         o   Vedanta came to be the dominant current of Hinduism in
             the post-medieval period.
         o   Brahma is the reality of life and rest all is Maya
         o   Atma is similar to Brahma and if a person achieves
             knowledge of self, he would understand brahma and that
             will lead to salvation.
         o   Shankaracharya: Brahma is without attributes and
             knowledge is the way to reach salvation
         o   Ramanuja: Brahma possesses attributes and devotion leads
             to salvation
         o   All 5/6 methods allowed (depending on sub form)

                        Monism — atma and parmatma in the same
                         person
                        4 Mutts: Badrinath, Puri, Dwarka, Sringari

                        Merger of Atma and Paramatma is too difficult
                 o   Shuddha dvaita by Vallabhacharya
                               Impossible to merge atma and parmatma
                               Only through Bhakti, you can get close to
                                parmatma.
                               Philosophy merged with religion
Of the historical division into six darsanas, only two schools, Vedanta and Yoga,
survive.
Heterodox Philosophy:
They do not believe in God and authenticity of the Vedas.
       1. Cārvāka: Brihaspati
                 o   Mentioned in Vedas — Brihadarankya Upanishad
                 o   Didn’t survive.
                 o   Philosophy of Hedonism / materialism
                 o   Lokāyata: — more geared towards common people, hence
                     the name
                 o   Only Philosophy which doesn’t believe in atma and
                     reincarnation.
                 o   They consider only 4 elements of universe as Ether cannot
                     be experienced
                 o   Buddha contemporary: “Ajita Keshakambli"
       2. Ājīvika: Gosāla
                 o   Niyati: Philosophy of destiny, faith and fatalism
                 o   No need to do any action, you’ll get what the fate has for
                     you
                 o   Popularity in the Mauryan Period: “Bindusar" (Ashoka’s
                     father followed this school)
                 o   Barabara hills near Bodhgaya: Caves donated by Ashoka to
                     Ajivika monks
       3. Buddhism
       4. Jainism
Comparison between Buddhism and Jainism:
          Believed both were same but they weren’t
          Similarities:
                  o   Same region, Both were princes in real, Both against
                      Brahmanical rituals
          Difference:
                  o   Jainism: extreme form of conduct
                  o   Buddhism: Middle Path like you can eat meat if you don’t kill
                      the animal yourself.
          Buddhism went outside India but Jainism stayed confined to India
          Buddhism disappeared in India due to middle path.
          Over time, Buddhism tilted towards Hinduism (emergence of idolatry)
           and merged with it.
          Jainism survived due to strict code of conduct and individuality.
Out of these nine systems, eight are atheistic as there is no place for God
in them. Only Uttara Mimansa, which is also called Vedanta, has a place for
God in it.
Materialist View: Samkhya, Vaishiska, Ajivikas, Charvaka
Idealist: Overshadowed materialism — recommended rituals and spiritualism. It
hindered scientific inquiry and rational thinking.
