大乘起信論別記 1.101

1.101

言「依於智」者，依前智相，相續始生也。所依是細，唯一捨受，能依是麁，具起苦樂，故言生起苦樂。又所依智相，內緣而住，似眼；此相續識，遍馳外境；如覺故，言覺心起念，起念即是法執分別。識蘊與此麁執相應，遍馳諸境故，言「相應不斷」故。

As for "based on cognition," based on the preceding characteristic of cognition, continuity begins to arise. That which is relied upon is subtle, being exclusively equanimous feeling; that which relies upon it is coarse, fully producing suffering and pleasure, hence it is said to produce suffering and pleasure. Furthermore, the characteristic of cognition that is relied upon abides by inwardly cognizing objects, like an eye; this continuous consciousness runs universally to external objects, like awakening. Therefore it is said that the awakening mind gives rise to thoughts; giving rise to thoughts is precisely the discrimination of attachment to dharmas. The aggregate of consciousness is associated with this coarse grasping and runs universally to all objects; hence it says "constantly associated without interruption."
