Look not for refuge to anyone beside yourself. Heed fast to the truth as a lamp.

Wherever a person goes, his deeds, like a shadow, will follow.

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

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.

What you have become is the result of what you have thought

I will purify my bodily actions through repeated reflection. I will purify my verbal actions through repeated reflection. I will purify my mental actions through repeated reflection. That's how you should train yourself.

Purity or impurity depends on oneself, no one can purify another.
