首楞嚴義疏注經 4.58

4.58

In the Awakening of Faith, this is called the mark of turning (parāvṛtti-lakṣaṇa); thus the treatise states: "Because it relies on movement, it can see; without movement, there is no seeing." 'Turning' means arising: it turns from the preceding moving mind to arise, thereby constituting the capacity to see. Now, when it says "different from that which it differentiates," the active differentiator is the mark of identity, and that which is differentiated is the mark of difference. Wishing to differentiate the mark of difference, one must establish the designation 'identity'. The former [mark of difference] was differentiated from reality; the present [mark of identity] is differentiated from difference, establishing identity in opposition to difference; furthermore, it is coarse and manifest. It is also called the mark of stillness, because stillness differs from movement. This stillness opposes movement and is not absolute stillness; therefore, it is said: "Due to difference, identity is established."
