The mind is everything. What you think you become.

Mind precedes all mental states. Mind is their chief; they are all mind-wrought. If with a pure mind a person speaks or acts happiness follows him like his never-departing shadow.

Be devoted to heedfulness. Guard your mind.

All experiences are preceded by mind, having mind as their master, created by mind.

Species do not grow more perfect: the weaker dominate the strong, again and again-the reason being that they are the great majority, and they are also cleverer. Darwin forgot the mind (- that is English!): the weak possess more mind. ... To acquire mind, one must need mind-one loses it when one no longer needs it.

The tired parts of the mind can be rested and strengthened not merely by rest, but by using other parts.
