成唯識論述記 2.511

2.511

述曰：非擇無為體是一者，一法緣闕得不生時，應於一切法得非擇滅；以非擇體唯是一故；如已所得非擇之法。問：何故難空？令色中有空；次難令亦得餘部品擇滅；後難令亦得餘法非擇滅。

The Commentary states: If the substance of the unconditioned cessation not through deliberation were one, then when a single phenomenon lacks conditions and attains non-arising, one should attain cessation not through deliberation regarding all phenomena, because the substance of non-deliberation is solely one—just like the phenomenon of non-deliberation already attained. Question: Why first refute space by forcing that there is space in form; next refute it by forcing that one would also attain the cessation through deliberation of other categories and grades; and finally refute it by forcing that one would also attain the cessation not through deliberation of other phenomena?
