If you can't spot the difference I don't know what to tell you.
Ugh, now you're just knit-picking. There's nothing Masonic/Satanic about putting your fingers together in that position. If you practice or learn meditation you will learn these things, a lot of it is actually just hidden knowledge. It's natural maybe I shouldn't have said common, fair enough. Most people couldn't care less about learning these things though. When I try to teach people or show them that I can do 30+ pushups without taking a single breathe they still don't care.
Monks sacrificed most of their time meditating on mountains and learning this stuff. Similar to breathing techniques that can bring you into certain states of mind or drastically improve physical performance. You're not born with a manual on how to operate your body so it took time to learn all these things.
Study traditional chinese medicine and the works of the brahmacharyan yogis of India, they figured all of this stuff out thousands of years ago.
