Mind is the manifestation as well as the seat of avidya. Mind should be disciplined, purified, and silenced. Therein is the way to cross the plane of illusion. Study and scrutiny of one’s own mind is the most profitable discipline. Just as a mother bestows all her tender love and watchful care in rearing up her beloved child born of prayer and patience of many years, just as her attentive gaze is always on it to see that it does not falter or fall anywhere, so too, nay, with a care thousand times greater than this, you should watch the movements of your mind.
