Your worst enemy is your best teacher.

If a viper lives in your room and you wish to have a peaceful sleep, you must first chase it out.

Better than a meaningless story of a thousand words is a single word of deep meaning which, when heard, produces peace.

The mind is the source of happiness and unhappiness.

We are what we think.

Look upon him who shows you your faults as a revealer of treasure: seek his company who checks and chides you, the sage who is wise in reproof: it fares well and not ill with him who seeks such company.

The heavens and the earth may be captured by the mind's eye.
