成唯識論演祕 4.487

4.487

釋曰：無漏定心而緣真如名無想定。或相應捨被惑所雜，或為緣縛，能雜能緣捨根惑種名捨麁重，斷此惑種名斷隨眠。據此等斷名斷捨根，非斷現受，餘文可悉。

The explanation states: An uncontaminated concentrated mind taking thusness as object is called the signless concentration. Either the associated equanimity is mixed with defilements, or it is bound by conditions; the seeds of defilement that can mix with or condition the faculty of equanimity are called the gross heaviness of equanimity, and abandoning these defilement seeds is called abandoning the dormant tendencies. In terms of abandoning such things, it is called abandoning the faculty of equanimity; it is not abandoning manifest feeling. The remainder of the text can be understood.
