Admonition

Not to do evil, to cultivate good, to purify one's mind,--this is the Teaching of the Buddhas.

Forbearing patience is the highest austerity, Nirvana is supreme, say the Buddhas. He, verily, is not a recluse who harms another. Nor is he an ascetic who oppresses others.

Not insulting, not harming, restraint according to the Fundamental Moral Code, moderation in food, secluded abode, intent on higher thoughts,--this is the Teaching of the Buddhas.

---The Dhammapada 183-184---

When questioned by the Venerable Ananda as to how the previous Buddhas had observed the Uposatha (Holy Day), the Buddha replied that all the Buddhas had recited these three verses in admonition.
