唯識二十論述記 1.86

1.86

述曰：下正敘難，初略頌，後廣問。頌中初句，牒大乘義，及第四句，「不應成」言，正為難理，總通四難。謂若說識無實境者，即處決定不應成等，至下當知。舊論頌云：「處、時悉無定，無相續不定，作事不應成，若唯識無塵」，意具文倒，尋者自知。

The Commentary says: Below, the objection is properly related: first the verse is briefly presented, and then the inquiry is extensively stated. In the verse, the first line quotes the Mahāyāna thesis, and together with the phrase 'should not be established' in the fourth line, it constitutes the actual reasoning of the objection, which applies universally to all four objections. That is, if it is said that consciousness is without a real object, then spatial determination should not be established, and so forth, as will be understood below. The verse in the old translation says: 'Space and time are entirely undetermined; / there is no non-determination of stream; / the performance of actions should not be established, / if there is vijñapti-mātra without dust.' Its meaning is complete, but the phrasing is inverted, as one who investigates will naturally know.
