成唯識論述記 5.841

5.841

述曰：舉喻已顯，此亦如是。何故相應？唯說遍行等屬心，不說心屬於受等耶？為答此問，因解第二行相之門與心同異。

The Commentary states: Having adduced an analogy to make it clear, this is also like that. Why, in association, are only the omnipresent factors and so forth said to belong to citta, while citta is not said to belong to feeling and so on? To answer this question, [the text] consequently explains the second section on the ākāra, their sameness and difference with citta.
