In that case, there is no difference between Gautama Buddha and Tony Robbins.
Well there's certainly a difference in the content of the teachings and in the place they play, and have played, in world culture.
...if you really don't think that Buddha is reincarnated...
I don't believe in reincarnation. Or any Christian afterlife. Or Valhalla. Or the Islamic Paradise. It's simply a human conceit to make us feel better about the short time we get to live here.
...or that this stuff about enlightenment is nothing more than some pop-psychology principle...
I really wouldn't describe it as a "pop-psychology principle" or a "supermarket self-help program" — it doesn't offer riches, popularity with the opposite sex, or salvation.
...then I concede that Buddhism is not a religion.
I'm not asking you to concede that. It is
a religion, it just doesn't require a supernatural world view or faith in the power and benevolence of a Supreme Being.
My objection is to the idea that Buddhism is somehow superior to other religions.
Well I've never made that claim. I've only tried to show that it is accessible without belief in gods, spirits, and angels. Maybe that makes it inferior
to other religions!
If Buddha isn't being presented as some absolute truth... then I can tolerate it.
Spoken as a true man of the world.
