俱舍論記 17.87

17.87

「有餘師說至其命方斷」者，敘異說。天亦害天，知過去世為怨讐故。斬首、截腰其命方斷。故《正理》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。」

"Other masters say: up to their life is then severed": this relates an alternative explanation. Devas also harm devas, knowing that they were enemies in past lives. Only when their heads are cut off or their waists severed is their life severed. Therefore the *Nyāyānusāra* says: 'Other masters say: Devas also kill devas. Although when a deva's limbs are severed they grow back again, if the head is cut off or the torso severed in the middle, they do not grow back.'
