八識規矩補註 2.3

2.3

此言第七於三性中唯無記性，於四性中乃有覆無記（此「四」欲界全具，上二界唯三，除不善故。覆者，謂染法，障聖道故，又能蔽心令不淨故。此非善惡，故名無記），以性非順益違損故，恒與四惑俱故。故云，有覆四惑者，謂我癡（謂無明，愚於我相迷無我理，故名我癡也）、我見（謂我執於，非我法妄計為我，故名我見也）、我慢（謂倨傲，恃所執我令心高舉，故名我慢也）、我愛（謂我貪，於所執我深生耽著，故名我愛也）。此識於三境中唯緣帶質，以心緣心故，解見上文。上「心」字目見分，下「心」字目本質，謂此相分帶本質生，故名帶質。或曰：「此相分亦帶見生，何不云帶情境耶？」為濫獨影是故不爾。

This states that the seventh [consciousness], among the three natures, is solely of the avyākṛta nature, and among the four natures it is nivṛtāvyākṛta. (These "four" are fully present in the desire realm, while the upper two realms have only three, because the unwholesome is excluded. "Covered" refers to defiled dharmas, because they obstruct the noble path and can veil the mind to make it impure. Because this is neither wholesome nor unwholesome, it is called avyākṛta.) This is because its nature is neither beneficial nor harmful, and because it is constantly accompanied by the four afflictions. Therefore it is said [to be nivṛtāvyākṛta]. As for the four afflictions, they are self-delusion (meaning ignorance: being foolish about the characteristic of a self and confused about the principle of selflessness; hence called self-delusion); self-view (meaning ātmagrāha: falsely calculating non-self dharmas to be a self; hence called self-view); self-conceit (meaning arrogance: relying on the apprehended self to make the mind haughty; hence called self-conceit); and self-love (meaning self-greed: generating deep attachment to the apprehended self; hence called self-love). This consciousness, among the three realms [of objects], grasps solely an image with real base, because mind grasps mind, the explanation of which was seen above. The former word "mind" designates the darśanabhāga, and the latter word "mind" designates the original referent. Because this nimittabhāga arises bearing the original referent, it is called [an image] with real base. Someone may ask: "This nimittabhāga also arises bearing the darśana[-bhāga]; why not call it a realm that bears the subjective mind?" It is not so in order to avoid confusing it with the solitary image [realm].
