成唯識論述記 3.776

3.776

述曰：今顯此識唯如來有，無漏善法不可熏故，即顯無漏諸法種子，皆是因中已熏滿足，佛果已去更無熏習，前佛後佛無差別故，功能齊故。若受熏時，功德異故，如《佛地論》有為無漏皆不受熏，是無漏故，如涅槃等。金剛心菩薩等既有二說，若已起者，時少故不說。

The Commentary states: This shows that this consciousness exists only in the Tathāgata, because anāsrava wholesome dharmas cannot be perfumed; this shows that the seeds of all anāsrava dharmas have already been fully perfumed while in the causal stage. Once the buddha-fruit is reached, there is no further perfuming, because there is no distinction between earlier buddhas and later buddhas, their functional capacities being equal. If it received perfuming, their merits would differ. As the Buddhabhūmi-śāstra states, conditioned anāsrava [dharmas] never receive perfuming, because they are anāsrava, like nirvāṇa and so forth. Since there are two theories regarding bodhisattvas in the vajropama-samādhi, if it has already arisen, it is not mentioned because of the briefness of the time.
