釋門歸敬儀 2.30

2.30

已前約相，且列十條，餘有曲身低頭、注目瞻仰，隨心機用，何可備之？然一以貫之，多陷前列，至於律制，頗亦殊倫。故下座之禮，先備五法：一、偏袒；二、脫屣；三、禮足，四、互跪，五、合掌也。上座於下座前悔則有四法，除其禮足，是知餘四通於尊卑。禮足一法，不行下位，此謂懺罪，故立四儀。自餘常時，四法都削。（下座互跪，亦據請悔之儀，常途修承，理不行也。）

The above has briefly laid out ten items according to external forms. As for others, such as bending the body, lowering the head, and fixing the gaze in upward reverence, which are employed according to the mind's inclinations, how could they all be recorded? Yet when unified by a single thread, most fall within the preceding ranks; as for the Vinaya prescriptions, they are also quite distinct in category. Therefore, the etiquette of a junior seat first comprises five methods: first, baring the right shoulder; second, removing the shoes; third, bowing at the feet; fourth, alternating kneeling; and fifth, joining the palms. When a senior seat repents before a junior seat, there are four methods, omitting bowing at the feet; hence we know that the other four apply to both high and low. Bowing at the feet alone is not practiced toward a lower position; these four rites are established for repenting transgressions. At all other ordinary times, all four methods are eliminated. (The alternating kneeling of a junior seat is also based on the rite of making requests and repenting; in ordinary cultivation and reception, it is not logically practiced.)
