Often in the casual remarks of great men one learns their true mind in an intimate way.

A man can wear out a particular part of his mind by continually using and tiring it, just in the same way he can wear out the elbows of his coat.

Where the mind is without fear and the head is held high Where knowledge is free.

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.

Whatever an enemy might do to an enemy, or a foe to a foe, the ill-directed mind can do to you even worse.
