首楞嚴義疏注經 10.325

10.325

牒指識體也。初三句牒計也。行人所認微細明了、離行生滅、堪然不動、目為常住者，即識陰也。於身下指體也，識陰豈越見聞覺知？此約用指也。

This restates and identifies the substance of consciousness. The first three lines restate what is imputed: what practitioners recognize as subtle clarity, free from the arising and cessation of formations, serenely unmoving, and regard as permanently abiding, is precisely the aggregate of consciousness. From "within the body" onward identifies its substance: does the aggregate of consciousness ever exceed seeing, hearing, sensing, and knowing? This points to it in terms of function.
