首楞嚴義疏注經 3.158

3.158

破有知也。初句奪成心量，離心之法若有知者，應名為心。異汝下更分即異以破，初二句破異。有知之法若異汝心，即同他人，異於汝心又有知故。即汝下三句破即心，初句半牒半定，後二句破。有知之法既即汝心，即應汝心之外更有汝心也，故云更二於汝。

Refuting their being conscious. The first line strips them of their status to make them mental capacity: if dharmas apart from the mind were conscious, they should be called mind. From 'being different from you' onward, it further distinguishes identity and difference to refute them; the first two lines refute difference. If conscious dharmas were different from your mind, they would be identical to another person, because they are different from your mind and yet conscious. The three lines from 'if they were identical to you' refute identity with the mind; the first line half-cites and half-determines, and the latter two lines refute it. Since conscious dharmas would be identical to your mind, that would mean that outside your mind there is yet another mind of yours, hence it says: 'duplicated apart from you.'
