唯識二十論述記 2.77

2.77

述曰：此破小乘微不成中，結不成也，「是」者指前；「故」者所以。由前我說量過等，所以汝之所執一實微不成。

The Commentary says: In this refutation of the Hīnayāna paramāṇu being unestablished, this concludes its non-establishment. 'This' points to the preceding; 'therefore' indicates the reason. Because of the faults in the anumāna and so forth stated by me previously, your posited single real paramāṇu is unestablished.
