四分律行事鈔資持記 3.90

3.90

十中。初明著時或對佛僧，不得向背；理應側身，要須屏處。口銜手奮，恐污損故。《毘柰耶》中注云象鼻，即犯眾學不齊整戒。文注顯然，今皆垂肘，豈知步步越儀犯吉。今準《感通傳》，天人所示，凡經四制。世多迷執，略為引之。彼云：元佛初度五人，爰及迦葉兄弟，並制袈裟左臂，坐具在袈裟下；西土王臣，皆披白㲲，搭左肩上，故佛制衣角居臂異俗。（此一制也。）後徒侶漸多，年少比丘儀容端美，入城乞食，多為女愛，由是制衣角在肩後；為風飄，聽以尼師壇鎮之。（此二制也。）後有比丘為外道難言，袈裟既為可貴，有大威靈，豈得以所坐之布而居其上；比丘不能答，以事白佛；由此佛制還以衣角居于左臂，坐具還在衣下。（此三制也。）於後比丘著衣不齊整，外道譏言狀如婬女，猶如象鼻；由此始制上安鉤紐，令以衣角達于左臂（達即到也）；置於腋下，不得令垂，如上過也。（今須準此，乍可排著左肩；若垂臂肘，定判非法，步步結罪。舊云：今在左臂為正，但不得垂尖角者。非也。）

In the tenth [part], first it clarifies that when putting it on, if one is facing the Buddha or the Saṅgha, one must not face them directly or turn one's back to them; in principle, one should turn sideways, and it must be done in a secluded place. Holding it in the mouth and shaking it with the hands are prohibited for fear of defilement and damage. In the *Vinaya*, the note says 'elephant trunk', which violates the śaikṣa rule on not wearing the robe evenly. The text and notes are obvious; nowadays people all let it hang from the elbow, unaware that with every step they violate the deportment and incur a duṣkṛta. Now, according to the *Record of Resonant Communications*, what was revealed by the celestial being underwent four regulations in all. Since the world is largely deluded and clinging, I briefly cite it. It says: 'Originally, when the Buddha first delivered the five men and up to the Kāśyapa brothers, all were regulated to place the kāṣāya over the left arm, with the sitting mat under the kāṣāya. The kings and ministers of the Western lands all wore white fine cotton draped over the left shoulder, so the Buddha regulated the corner of the robe to rest on the arm to differ from the laity. (This was the first regulation.) Later, as the disciples gradually increased, young bhikṣus of handsome and fine appearance entering the city to beg for food were often loved by women; therefore, the robe corner was regulated to be behind the shoulder; because the wind blew it, it was permitted to weigh it down with the niṣīdāna. (This was the second regulation.) Later, a bhikṣu was challenged by non-Buddhists saying:
