成唯識論演祕 5.136

5.136

釋曰：追憶曾境名為隨念；憶別別境，名為別念，或初總相念；後別相念，憶不忘等，念之別名。如經說諸令心住與等住，安住近住及定住，不亂不散攝寂止，等持心住一緣性。

Explanation: Recollecting a past intentional object is called recollection (anusmṛti); recollecting distinct intentional objects is called distinct mindfulness; or initially general mindfulness, and later specific mindfulness; memory, not forgetting, and so forth are different names for mindfulness. As the sūtra says: "All making the mind abide, abiding equally, remaining firmly, abiding closely, and abiding stably, non-distraction, non-scatteredness, collecting and pacifying, samādhi, the mind abiding in a one-pointed nature."
