四分律行事鈔資持記 3.994

3.994

四中，初示正儀。次斥非法。律文但制五法，偏袒、脫屣、互跪、合掌、禮足，本無捉衣之式，復非尊敬之意；故特點之，絕後濫用。

Under [point] four: First, showing the correct ritual. Next, reproving what is not the Dharma. The Vinaya text only institutes five dharmas: baring the right shoulder, removing shoes, kneeling on one knee, joining the palms, and bowing to the feet. Originally there was no ritual of grasping the robe, nor does it express respect. Therefore, it is specifically highlighted to stop subsequent misuse.
