There are the mechanics,techniques, principles and the powers. The powers are generally taught in house or through transmission from an elder. It is the expression of the powers that are most impressive. The powers are ancestral and inherent in ones nature, a reflection of ones ancestry, hence we say some "got it honest". Unfortunately most of the ancestral powers passed down are suppressed or denied expression when seen out of context or the recipient is on able to "hold it". The modern tales if super heroes are merely stories on ancestors who expressed the powers. They are among us...LOL!
