首楞嚴義疏注經 2.171

2.171

前將八境以對妄見權示無還，由是則知本妙明心未嘗生滅，本有真性迷而不知，却執緣塵自取流浪。如前文云「由汝無始至于今生，認賊為子，失汝元常，故受輪轉。」然雖權指，意顯即是，以末不離本故。

Earlier, by contrasting the eight sensory objects with false seeing, he provisionally demonstrated that there is nowhere to return. From this one knows that the original, wondrous, bright mind has never arisen or ceased; yet being deluded about the inherently possessed true nature and failing to know it, one instead grasps conditioned dust and brings about one's own wandering. As an earlier passage states: 'Because from beginningless time until your present life you have recognized a thief as your son and lost your original permanence, you undergo transmigration.' Although he points it out provisionally, the intention is to reveal that it is precisely this, for the branch is not separate from the root.
