[66] "Bhikkhus, thus has the Dhamma been well proclaimed by me — made plain, laid open, made known, with the patchwork cut away (chinnapiloṭiko). Bhikkhus, when the Dhamma has thus been well proclaimed by me — made plain, laid open, made known, with the patchwork cut away — it is fitting indeed for a clansman who has gone forth out of faith to arouse energy (vīriya) thus: 'Gladly, let only skin, sinews, and bones remain; let the flesh and blood in this body dry up. So long as that which is to be attained by manly strength, by manly energy, by manly exertion has not been attained, there shall be no slackening of a man's energy.' Bhikkhus, the lazy person dwells in suffering (dukkha), mingled with evil, unwholesome states, and he lets a great personal good waste away. But one who has aroused energy, bhikkhus, dwells happily, secluded from evil, unwholesome states, and he fulfills a great personal good. Bhikkhus, it is not by the inferior that the supreme is attained; it is by the supreme that the supreme is attained. Bhikkhus, this holy life is the cream worth drinking; the Teacher is present in person."
