首楞嚴義疏注經 1.624

1.624

此舉盲者得眼光時，因眼顯照前塵境界，心方得見。以前例此，應知見性是心非眼也。窮其根本見性元心，遽遽相推，心為其主，餘是助因。以常情只知眼見，不識是心，今此且令知其根本，未辨真妄。

This mentions the blind person gaining eyesight: because the eye manifests and illuminates the realm of the front dust, the mind then gets to see. Analogizing this with the former, one should know that the seeing nature is the mind, not the eye. Investigating its root, the seeing nature is originally the mind; tracing through their relations, the mind is the master, and the rest are auxiliary causes. Because ordinary sentiment only knows that the eye sees and does not recognize that it is the mind, here [the Buddha] temporarily causes him to know its root, without yet distinguishing the true from the false.
