首楞嚴義疏注經 4.58

4.58

《起信》名為轉相，故論云「以依動故能見，不動則無見。」轉者，起也，轉前動心起，成能見故。今言異彼所異者，能異即同相，所異即異相。欲異異相，須立同名。前異於真、今異於異，待異立同；又麁顯故。亦名靜相，靜異動故。此靜待動，非絕待靜，故云因異立同。

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."
