唯識二十論述記 1.270

1.270

述曰：此正難也。既言一切諸法皆無，即無有識。唯識既無，今此論中何所安立得入佛果？其安立者，即牒論初立宗言問，義同前釋。

The Commentary says: This is the actual objection. Since you say that all phenomena are completely non-existent, then consciousness does not exist either. Once vijñapti-mātra is non-existent, what could be established now in this treatise through which one could enter into the fruition of buddhahood? 'What could be established' refers back to and questions the formulation of the pratijñā at the beginning of the treatise; its meaning is as explained before.
