四分律刪繁補闕行事鈔 2.209

2.209

展轉食戒三十二。《十誦》云數數食；《五分》同之；《僧祇》云處處食。總一明判，云背請戒。五緣：一先受五正請，不問道俗親非親，二食境堪飽足，三無緣謂病等也，四更異主受正食，五隨咽便犯。律中，請有二種：若僧次，若別請也。食者，飯、[麩-夫+少]、乾飯（稠粥亦是）。《僧祇》云：初出釜，畫不成字，是非正食。《僧祇》：若到俗家，言闍梨今日我家食，即名請處。若作食未熟，欲往他家，應白已去；不白去者，至彼得正食，犯二墮：一不白請家，二是背請。大同《四分》。又律云：病者不堪一坐食，令足。施衣時者，十二月中，隨有衣食請處，開背。若一日受眾多請，自受一請，餘者施人，言：「長老我應往彼，今布施汝。」若不者，背前家，咽咽墮；背後家，咽咽吉。《五百問》云：若主人嫌代去者不得。《十誦》、《多論》：前家不得隨病食，背至第二第三家，漸漸食至日中，不得到第四家。律不犯者：病時，施衣時，若捨請，若請與非食（謂粥餅不正食），或不足（是正而少不足），或無請，或食已更得食等，不犯。

Precept thirty-two: eating in succession (paramparābhojana). The Daśādhyāya-vinaya calls it 'eating repeatedly'; the Pañcavargika-vinaya agrees with it; the Mahāsāṃghika-vinaya calls it 'eating in different places.' Summing them up in a single clear determination, it is called the precept against reneging on an invitation. There are five conditions: first, having previously accepted an invitation to the five staple foods, regardless of whether from a monastic or layperson, a relative or non-relative; second, the food presented being sufficient to satisfy hunger; third, the absence of valid reasons (meaning illness, and so forth); fourth, receiving staple food again from a different host; fifth, an offense is incurred with every swallow. In the Vinaya, invitations are of two types: either by monastic rotation or by individual invitation. The foods are: cooked rice, parched grain flour, dried boiled rice (thick porridge is also included). The Mahāsāṃghika-vinaya states: 'When freshly taken out of the cauldron, if a character drawn on it does not form, this is not staple food.' The Mahāsāṃghika-vinaya states: 'If one arrives at a layperson's house and they say, "Master (ācārya), eat at my house today," that constitutes an invitation.' If the food being prepared is not yet cooked and one wishes to go to another house, one must notify them before leaving; if one leaves without notifying them and obtains staple food upon arriving there, one commits two pāyattikas: first, failing to notify the inviting host; second, reneging on the invitation. This largely agrees with the Dharmaguptaka Vinaya. Furthermore, the Vinaya states: 'The sick are not able to eat enough at a single sitting to be satisfied.' As for the time of giving robes: within the twelve months, wherever there is an invitation for robes and food, an exception is made to renege. If one receives multiple invitations in a single day, one accepts one invitation for oneself and confers the rest upon others, saying: 'Venerable, I should have gone there; I now bestow it upon you.' If not, reneging on the former household incurs a pāyattika with every swallow; reneging on the latter household incurs a duṣkṛta with every swallow. The Five Hundred Questions states: 'If the host is displeased with a substitute going, it is not permitted.' The Daśādhyāya-vinaya and the Sarvāstivāda-vinaya-vibhāṣā state: 'If one cannot eat according to one's illness at the former household, one may turn away and proceed to a second or third household, gradually eating until midday, but one may not go to a fourth household.' Those who do not commit an offense according to the Vinaya: during illness; during the time of giving robes; if the invitation is relinquished; if invited to non-staple foods (meaning porridge and cakes that are not staple food); or if insufficient (it is staple food, but too little to suffice); or if there was no invitation; or if after finishing a meal one receives further food, and so forth—there is no offense.
