I've known one Yazidi for a long time, and I think their Yazidi religion/culture is very much similar to Hinduism, India should help these Yazidis and settle them in India. 🙏
Similarities in a sense:
1. Yazidis worship God 'Melek Tawwus' (In Hinduism known as 'Kartikeya', Peacock symbols both have)
2. April 14 Yazidi New Year (Hindu New Year also)
3. They made a mouth sound in their celebration (In Hinduism known as 'Ululudhvani, Ululation')
4. Yazidis have a symbol similar to Bindi or Tilak during temple prayer, very similar to Hindu forehead custom.
5. Does fire ritual (Very common in Hinduism and core of Zoroastrianism)
6. Yazidis do not circumcise, a very rare thing in the Arab culture (Hindus also do not circumcise).
7. Prays with folded hands (Just like the Hindus).
8. Believe in a recurring birth and death cycle (Dharmic philosophy of 'punar janam' or reincarnation)
9. The oil lamps called 'Sanjakas' that the Yezidis use are very similar to 'Arti' used in the Hindu culture for worship.
10. The Yazidi temple shrines or 'Lalish' are of pyramid structure, which are quite similar to Hindu Temple architecture.
11. Yazidis pray at sun rise and sun set, just like Hindus. Both face the rising or setting sun when praying to sun.
And these are just a few similarities, I'm pretty sure there are many more, we just need to re-establish the broken links, I believe Yazidis were once linked with Hindus of the Indian peninsula but got separated because of natural calamities and Islamic Invasions and Influence.
