A Sense of Danger in the Least Offence
19. If a Bhikkhu should desire, Brethren, by the destruction of the great evils, by himself, and even in this very world, to know and realise and attain to Arahatship, to emancipation of heart, and emancipation of mind, let him then fulfil all righteousness, let him be devoted to that quietude of heart which springs from within, let him not drive back the ecstasy of contemplation, let him look through things, let him be much alone!’
20. ‘Continue therefore, Brethren, in the practice of Right Conduct, adhering to the Rules of the Order; continue enclosed by the restraint of the Rules of the Order, devoted to uprightness in life; train yourselves according to the Precepts, taking them upon you in the sense of the danger in the least offence. For to this end alone has all, that has been said, been said!’
21. Thus spake the Blessed One. And those Brethren, delighted in heart, exalted the word of the Blessed One.
