As in all infant sciences, the universal habit of the human mind - to take a partial or local truth, generalise it unduly and try to explain a whole field of nature in its narrow terms - runs riot here (in psychoanalysis).

Yoga is a generic name for any discipline by which one attempts to pass out of the limits of one's ordinary mental consciousness into a greater spiritual consciousness.
You carry in yourself all the obstacles necessary to make your realization perfect. If you discover a very black hole, a thick shadow, be sure there is somewhere in you a great light. It is up to you to know how to use the one to realize the other.

Of that which is in mortal in mortals, and possessed of the truth, is a God and established inwardly as an energy working out in our divine powers....
