泰云：浪嗜名鼠狼，鼠狼尾多，蛇欲嚇時以尾障蛇口，蛇不得囓，無明亦障於聞知，不得聞法。

Tai says: *Lángshì* is called a weasel; the weasel has a large tail, and when a snake tries to strike, it blocks the snake's mouth with its tail so the snake cannot bite; ignorance likewise obstructs hearing and knowing, so that one cannot hear the Dharma.
