Buddhism

The core of Siddhartha Gautama's teachings have nothing to do with belief in gods or "reincarnation" as the term is normally used. He, like nearly all Indians at the time, believed in those things, though, and they got needlessly mixed into the dogmas of most Buddhist sects.

He once had a bunch of townspeople being bamboozled by some Brahmins come up to him and asked for his advice. he told them to not be mislead by intellectual authority or be convinced by ideas that merely seemed reasonable but had no evidence to back them up. He also told them that questions about the Hereafter were useless to Enlightenment. He believed in Reincarnation but said that if there were no reincarnation it would not affect his teachings, because they are for happiness in this life.
