68.9

疏「此用深空滅離二我」者，即離彼我想，通於人法二我無也。云何為深？五地唯約淨法說十平等，今直說深空。又前是加行觀察，今已住空般若現前故；二四地道品有身受等故；三此地初用十平等，十相未泯故。

Regarding the commentary's "This uses profound emptiness to eliminate and separate from the two selves": that is, separating from the notion of that self applies universally to the non-existence of both the personal and dharmic selves. Why is it called profound? The fifth stage solely speaks of the ten equalities in terms of pure dharmas; now it directly speaks of profound emptiness. Furthermore, previously it was applied contemplation, whereas now one already abides in emptiness and prajñā is manifest; second, the bodhipakṣadharma of the fourth stage involves the body, feeling, and so forth; third, the beginning of this stage uses the ten equalities, wherein the ten signs are not yet obliterated.
