Ever heard of logical contradictions?....where if one claim is true the opposite cannot be true. Brahman in Hinduism is not the same as Yahweh as described in the bible. If one is true, the other must be false...or both are false. Both cannot be true.
Maybe all of them have a lot of truth in them and were pretty similar to begin with. Truth that has been obscured by those that amend the original and sell their version to control, maintain societal stratification, and last but not least cash in and live as a parasite on the masses. I know Hindus and Moslems that accept the teachings of Jesus which is more than several books of the New Testament do in ascribing teachings to Jesus that he never uttered and in fact contradicted. If an atheist reads this long thread and decides to remain an atheist, I understand.
Patriotism (and religion) is the last refuge of a scoundrel.
