俱舍論疏 17.92

17.92

論「雖諸天眾至其命方斷」，《正理論》云「有餘師說：天亦殺天，雖天身支斷已還出，斬首、中截則不更生，故欲天中有殺業道。」

Regarding the passage of the śāstra from "Although among the hosts of devas" up to "only then is their life cut off", the Nyāyānusāra says: "Other masters say: Devas also kill devas. Although when a deva's limbs are severed they emerge again, if their head is cut off or their trunk is bisected, they do not regenerate; therefore, in the desire realm heavens there is the course of action of killing."
