瑜伽論云。謂壽量極故○雜阿含經云。壽煖識三法捨離名死○唯識疏云。身壞命終。將入滅相。方名死緣。大乘宗滅相屬過去故○正法念處經偈云。不擇於貧富少壯。及老年。若在家出家。無不為死壞。

The Yogācārabhūmi-śāstra states: It means when the lifespan is exhausted. The Saṃyuktāgama states: The separation of the three dharmas—lifespan, warmth, and consciousness—is called death. The Weishi shu states: When the body breaks down and life ends, about to enter the characteristic of cessation, only then is it named the condition of death; this is because according to the Mahāyāna school, the characteristic of cessation belongs to the past. A verse in the Saddharmasmṛtyupasthāna Sūtra states:
"It makes no distinction between poor and rich, young, robust,
And old age;
Whether householders or renunciants,
None are not destroyed by death."
