成唯識論演祕 2.433

2.433

詳曰：《疏》釋正也，大小乘教無說能生名命根也，且《俱舍》頌曰：「命根體即壽，能持燸及識。」《雜集論》云：識蘊相續住時，決定令眾同分常得安住或百年等，名為命根。《瑜伽》、《顯揚》、《五蘊》等論，皆以住持而名命也。

Examination: The Commentary's explanation is correct. Neither Mahāyāna nor Hīnayāna scriptures state that what is able to produce is called the life-faculty. Moreover, the Kośa verse says: "The substance of the life-faculty is life itself; / it can sustain warmth and consciousness." The Abhidharmasamuccaya-bhāṣya states: "When the continuity of the consciousness aggregate has a determined duration, causing the generic similarity to always remain settled, whether for a hundred years or the like, it is called the life-faculty." Treatises such as the Yogācārabhūmi, the Prakaraṇāryavācā, and the Pañcaskandhaka all designate life on the basis of maintenance.
