大般涅槃經疏 23.8

23.8

From "How is morality cultivated?" onwards, thirdly, he explains morality, and the text has two parts: first, the morality of abandoning evil, namely [the vows of] cows, dogs, and the like, all grasping at their marks and keeping them. Non-Buddhists who attained supernormal powers saw that cows, dogs, and the like were reborn in heaven after death, and thereupon emulated their conduct in the hope of attaining rebirth in heaven; the rest are all analogous to this. Next is attaining good morality, as in the text.
