大乘百法明門論開宗義決 1.56

1.56

一緣慮義等者。然准四卷楞伽經注有二種心。一者質多緣慮之心。二者乾栗大貞實之心。八識皆名虛妄分別。攀緣思慮一切妄境。皆名質多緣慮心矣。既能變生一切諸法。是一切法貞實體相。是故亦名貞實心矣。

Regarding 'First, the sense of cognitive reflection', and so forth: according to the commentary on the four-fascicle Laṅkāvatāra-sūtra, there are two kinds of mind: first, the mind of cognitive reflection (citta); second, the mind of genuine reality (hṛdaya). The eight consciousnesses are all called false discrimination; all seizing upon and reflecting on false sense-objects are called the mind of cognitive reflection (citta). Since it can transform into and give rise to all dharmas, it is the genuine, real essence and characteristic of all dharmas; therefore, it is also called the genuine and real mind.
