俱舍論記 14.141

14.141

「謂盡智等至前後等故」者，答。謂佛身中盡、無生等，及彼隨行無漏五蘊，名無學。非色等身有漏五蘊，未成佛前及成佛後等相似故。

"Namely, the knowledge of destruction, etc. ... because before and after are equal" is the answer. That is, within the Buddha's body, the knowledge of destruction (kṣaya-jñāna), the knowledge of non-arising (anutpāda-jñāna), etc., and their concordant uncontaminated five aggregates (skandhas), are called aśaikṣa. It is not the physical body, etc., consisting of the contaminated five aggregates, because before becoming a Buddha and after becoming a Buddha they are equally similar.
