首楞嚴義疏注經 7.164

7.164

重指業相也。昧圓明真實，成能所虛妄。能所妄動本無因依，妄想發生，無同異中熾然成異，故無體也。

This points again to the mark of karma. Obscuring the reality of perfect luminosity, the falsehood of subject and object is formed. The false movement of subject and object originally has no cause or support; when false thinking arises, difference blazes forth within what has neither sameness nor difference; thus it has no substantial entity.
