1.305

三、次前明利心，即此三性是麁想現行故，細想現行無記心者，即我愛心，此說第六識。若兼第八即末後心，故說不能憶善惡法。

3. Prior to that, the clear and sharp mind: this belongs to the three natures, because it is the active manifestation of coarse thoughts. As for the indeterminate mind of the active manifestation of subtle thoughts, it is the mind of self-love, which is here spoken of as the sixth consciousness. If combined with the eighth, it is the final mind; hence it is said that one cannot remember wholesome or unwholesome dharmas.
