首楞嚴義疏注經 2.202

2.202

汝若執言：汝能見心同所見物亦有差別。斯則見即是物，佛之見性亦合是物，應被汝見。

If you cling to the statement that your mind capable of seeing is like the seen objects in also having distinctions, then seeing is simply an object, and the Buddha's nature of seeing should likewise be an object, and thus should be seen by you.
