成唯識論演祕 2.509

答：我宗無為亦立假想，故《大集經》第二十云：無為之法有三種相，謂無出、無滅、無住。《瑜伽》八十八云：有為是無常，三有為相施設可得。與此相違，應知常住無為三相，若爾何故不相應法但二十四？

Answer: Our school also establishes metaphorical characteristics for the unconditioned; hence Fascicle 20 of the Mahāsaṃnipāta-sūtra says: 'Unconditioned dharmas have three characteristics, namely, no arising, no cessation, and no abiding.' Fascicle 88 of the Yogācārabhūmi says: 'Conditioned phenomena are impermanent; the designations of the three conditioned characteristics are obtainable. Contrary to this, one should know the three characteristics of the eternally abiding unconditioned.' If so, why are there only twenty-four non-associated dharmas?
