首楞嚴義疏注經 3.158

3.158

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.'
