There is an Indian fable of three beings who drank from a river. One was a god; he drank ambrosia. One was a man; he drank water. One was a demon; he drank filth. What you get is a function of your own consciousness.

Yoga is the intentional stopping of the spontaneous activity of the mind substance. Now the notion is that within what is called the gross matter of the mind… there functions what we now call electricity.
