I'm trying to find more information as to how these internal arts were first discovered. I mean, they are way beyond scientific discovery, as western science barely recognizes the inner workings of these eastern arts. Are there any texts that explain where these ideas came from? Passed on from gods? Aliens? Some sort of divine being who had visions? I haven't yet seen any explanation on the matter. And the idea that someone would be able to discover internal alchemy, even with years of time to experiment, is still dumbfounding.
