26.29

又外道雖復邪僻持牛狗戒。既受戒已後必不犯。今出家人既受戒已。輕於毀犯。是二不及外道。

Furthermore, although non-Buddhists are depraved and observe vows of behaving like oxen or dogs, once they have taken their vows they will never violate them. Nowadays, those who have left the household, after taking their precepts, violate them lightly. This is the second way they fall short of non-Buddhists.
