大乘起信論別記 1.58

1.58

「覺於念住」者，住相之中，雖不能計心外有塵，而執人法因緣而住。法身菩薩覺人法相唯是識性，欲明所相心體，前覺異相，而眠於住相之夢，今與唯識真智相應，從住相夢而得覺悟，故言覺於念住。由得此覺，四種住相滅而不起故，言「念無住相」。

"Awakening to the abiding of thoughts": within the characteristic of abiding, although one cannot posit dust-objects outside the mind, one grasps the causes and conditions of persons and dharmas and abides [therein]. Bodhisattvas of the dharmakāya awaken to the characteristics of persons and dharmas being only the nature of consciousness. It intends to show that the mind-essence that is characterized, having previously awakened to the characteristic of change, was still asleep in the dream of the characteristic of abiding; now conforming with the true wisdom of consciousness-only, they attain awakening from the dream of the characteristic of abiding; hence it says "awakening to the abiding of thoughts." Because of attaining this awakening, the four kinds of the characteristic of abiding are extinguished and do not arise; hence it says "thoughts have no characteristic of abiding."
