11. This refers to the ascetic practice (dhūtaguṇa, sbyangs pa’i yon tan) of eating only what can be consumed in one sitting. The ascetic practices are an optional set of practices that mendicants can adopt to cultivate greater detachment. The list of practices varies in different sources. When thirteen practices are listed, they consist of (1) wearing patched robes made from discarded cloth rather than from cloth donated by laypeople; (2) wearing only three robes; (3) going for alms; (4) not omitting any house while on the alms round, rather than begging only at those houses known to provide good food; (5) eating only what can be eaten in one sitting; (6) eating only food received in the alms bowl, rather than more elaborate meals presented to the Saṅgha; (7) refusing more food after indicating one has eaten enough; (8) dwelling in the forest; (9) dwelling at the root of a tree; (10) dwelling in the open air, using only a tent made from one’s robes as shelter; (11) dwelling in a charnel ground; (12) satisfaction with whatever dwelling one has; and (13) sleeping in a sitting position without ever lying down.
