[964] **"He should know moderation here for the sake of contentment"** — as to "he should know moderation": he knows moderation for two reasons: through receiving or through use.
How does he know moderation through receiving? Even when little is given, he receives it out of sympathy for families, for the safeguarding of families, out of compassion for families; even when much is given, he receives a robe only sufficient for the maintenance of the body, he receives almsfood only sufficient for the maintenance of the belly. Thus he knows moderation through receiving.
How does he know moderation through use? Reflecting wisely, he uses the robe only for warding off cold, for warding off heat, for warding off contact with gadflies, mosquitoes, wind, sun, and creeping creatures, and only for the purpose of concealing the parts that arouse shame. Reflecting wisely, he uses almsfood not for amusement, not for intoxication, not for adornment, not for beautification, but only for the endurance and continuance of this body, for the termination of discomfort, and for assisting the holy life, thinking: 'Thus I shall terminate the old feeling (vedanā) and shall not arouse a new feeling; and there will be for me the keeping going of life, blamelessness, and dwelling in comfort.' Reflecting wisely, he uses the lodging only for warding off cold, for warding off heat, for warding off contact with gadflies, mosquitoes, wind, sun, and creeping creatures, and only for dispelling the perils of the seasons and for the purpose of delighting in seclusion. Reflecting wisely, he uses the requisite of medicines for the sick only for warding off arisen afflicting feelings, and for the utmost freedom from affliction. Thus he knows moderation through use.
As to "he should know moderation": for these two reasons he should know, should fully know, should discern, should distinctly discern, should penetrate moderation — hence, "he should know moderation."
