瑜伽師地論略纂 8.14

8.14

論云「如水所生雜穢𧍒牛，螺音狗行」，述曰：佛法如水，破戒比丘如水上眾多雜穢𧍒牛。又如狗高叫，似吹螺明，然有狗行，破戒亦爾，喻之。

The treatise says, "Like water-born filth-dwelling beetles and oxen, with the voice of a conch but the conduct of a dog": He comments: The Buddha-Dharma is like water; a monk who has broken the precepts is like the many filth-dwelling beetles and oxen upon the water. Furthermore, it is like a dog barking loudly, resembling the blowing of a conch shell, yet possessing the conduct of a dog; breaking the precepts is also like this—this is a metaphor for it.
