good and evil

Not to do evil, to cultivate the good, and to purify the mind.
This is the teaching of all the Buddhas.
 – The Buddha, The Dhammapada, verse 183

You who desire true life
and wish to walk on God’s path:
Depart from evil; do good;
seek peace with all your soul.
 – Psalm 34, adapted by Stephen Mitchell

Having done something evil,
Don’t repeat it,
Don’t wish for it:
Evil piled up brings suffering.

Having done something meritorious,
Repeat it,
Wish for it:
Merit piled up brings happiness.
 – The Buddha, The Dhammapada

Choosing to do good or evil
all depends upon whether I rely upon my One Mind.
 – The Mind of All Buddhas, Seon Master Daehaeng Sunim 

For one who at all times conclusively realizes the Buddha Mind, when he goes to bed, he goes to bed with the Buddha Mind; when he gets up, he gets up with the Buddha Mind…  He functions with perfect freedom in accordance with circumstances, letting things take their way. Just do good things and don’t do bad ones. If you pride yourself on good deeds, however, becoming attached to them and abominating the bad, that’s going against the Buddha Mind. The Buddha Mind is neither good nor bad, but operates beyond them both.
 – Bankei Yōtaku, (1622-93)

Thus the Master is available to all people
and doesn’t reject anyone.
He is ready to use all situations
and doesn’t waste anything.
This is called embodying the light.

What is a good man but a bad man’s teacher?
What is a bad man but a good man’s job?
If you don’t understand this, you will get lost,
however intelligent you are.
It is the great secret.
 – Tao Te Ching, translated by Stephen Mitchell

You are to be great teachers, freed from the ego; you must live only to serve all people. Desiring to become as a big tree or a great container of Wisdom prevents you from being a true teacher. Big trees have a big use; small trees have a small use. Good and bad bowls both have uses. Nothing is to be discarded. Keep both good and bad friends; this is your responsibility. You must not reject any element; this is Buddhism. My only wish is for you to free yourself from conceptions.
– Zen Master Kyong Ho

Good and evil have no self nature;
Holy and unholy are empty names;
In front of the door is the land of stillness and quiet;
Spring comes, grass grows by itself.
– Seon Master Seung Sahn

The one mind of all Buddhas is my one mind,
 inherently free of stain or purity.
 – A Thousand Hands of Compassion, Seon Master Daehaeng Sunim
