The spread to India is a modern deal. Zoroastrianism is an 18k yr old Persian deal. Zarathustra was really from Western Afghanistan.
Also there is an exoteric and esoteric Zoroastrianism. This is the only other account of a historical figure to have lived 18k years ago. From the same place and time. There was no other religious movement at that period. Just think. Ahura Mazda means Wisdom Light.
There are so many similarities with the story of Tonpa Shenrab Miwoche. It's very interesting.
Thanks for your post.
Yes there must be in every religion and philosophy similarities but that does not mean they are similar.
One great similarity between many religions is the factor or mentality Compassion.
Here do all agree, exept the Hedonists, non believers, nihilists etc., that one is only a human if we have compassion towards other sentient beings, Cosmological seen as a Buddhist of course.........
But that does not mean Christianity is = Bon.
I agree about all these similarities we can encounter worlwide between people and people who in turn are grouped in Religions etc. It shows similarities anyway because our mind is based on similarities , like emptiness
It are all colours but not the same.......
