瑜伽師地論略纂 8.43

8.43

論「不如象鼻」者，謂不垂袈裟角如象鼻，應搭膊上。　「如多羅樹房穗」，樹開出房穗，衣角亦爾，皆不應。「龍首」，謂雖搭膊上，不得角頭高如龍首；不得煩兔袈裟置曲肘中，如豆團相似。問。

Regarding the treatise's "not like an elephant's trunk": this means not letting the corner of the kāṣāya hang down like an elephant's trunk; it should be draped over the shoulder. "Like the tassel of a palm tree's spathe": when the tree blooms it puts forth a tassel from its spathe; the corner of the robe is the same, and both should not be done. "Dragon's head": this means that although it is draped over the shoulder, the corner end must not be raised high like a dragon's head; one must not roll up the kāṣāya and place it in the crook of the elbow, resembling a bean dumpling. [This requires] inquiry.
