So as a religion, Buddhism involves a lot of meditating and moderation, and there aren't that many fun rituals, and if you're a Buddhist monk, you don't get to have power like most holy people do. You have to renounce everything, including your hair. And yes, some of them get to be Kung Fu monks, but only in China, where Buddhism eventually migrated and became a religion with fun rituals and all kinds of great stuff that Siddhartha Gautama probably wouldn't have even recognized. But we're not talking about fun, populist religion. We're talking about old-school, ascetic Buddhism. Sure, you might be happy and fulfilled if you follow the Eightfold Path, but from everything we've learned so far, it would appear that humans don't want to be happy and fulfilled, or else they never would have stopped foraging. But Buddhism was very attractive if you were a low-caste Hindu, because there was no caste system.
