The Buddha spoke further, advising the monks to keep the rules of the order of monks. Then he asked three times if any among them had any questions. Do not be given to remorse later on with the thought: "The Master was with us face to face, yet face to face we failed to ask him." But no one spoke. The Buddha assured all of the monks they would realize enlightenment.
Then he said, All compounded things are subject to decay. Strive with diligence. Then, serenely, he passed into Parinirvana.
