首楞嚴義疏注經 3.156

3.156

牒計雙徵也。初二句牒，則法下徵。此法既離於心，更以知、不知徵而破之。

Citing the assertion and questioning both alternatives. The first two lines cite [the assertion], and from 'would the [self-nature]' onward questions it. Since these dharmas are apart from the mind, it further interrogates and refutes them on the grounds of being conscious or non-conscious.
