Abandon wrongdoing. It can be done. If there were no likelihood, I would not ask you not to do it. But since it is possible and since it brings about blessing and happiness, I do ask of you: abandon wrongdoing.

Cultivate doing good. It can be done. If it brought deprivation and sorrow, I would not ask you to do it. But since it brings blessing and happiness, I do ask of you: cultivate doing good.

-- The Buddha, Anguttara Nikaya
