四分律行事鈔資持記 1.1223

1.1223

次科，上座法中，初修敬者。律因六群反抄衣，衣纏頸裹頭，通肩披衣，著革屣；地上坐，床上坐自恣；佛因制具儀。律列四禮，文略脫屣；偏袒一法，此土不宜。僧隨上座者，律因上座具儀自恣，餘人猶故在座，佛又制之；此亦據五德來時，非謂大眾齊跪；《十誦》捉足者，投身仆地，舒手執足，示敬之極；彼又云：若是下座，不得執足，乖儀式也。

In the next heading, concerning the protocol for the senior seated monk, first, regarding cultivating reverence: because the ṣaḍvargika monks folded back their robes, wrapped their necks and heads in their robes, wore their robes covering both shoulders, wore leather sandals, and performed pravāraṇā while sitting on the ground or sitting on beds, the Buddha accordingly instituted the proper protocol. The Vinaya lists four courtesies; the text omits removing the sandals; the practice of baring one shoulder is not appropriate in this land. Regarding the sangha following the senior monk: because when the senior monk performed pravāraṇā with full etiquette, the others still remained in their seats, the Buddha also instituted this; this also refers to the time when the [monks of] five virtues arrive, and does not mean that the whole assembly kneels simultaneously. The Daśādhyāya-vinaya's 'grasping the feet' means casting oneself to the ground, extending one's hands to hold the feet, showing the utmost reverence. It also says: 'If it is a junior monk, he must not hold the feet, as that violates the protocol.'
