成唯識論述記 1.455

1.455

述曰：總結違宗，是則大為因，慢為果；五唯量、五大、十一根無差別故；皆不成也。

The Commentary states: This concludes generally [showing] the contradiction of their thesis: in that case, mahat is the cause, and ahaṃkāra is the effect; because the five tanmātras, the five mahābhūtas, and the eleven indriyas would be undifferentiated, none of them could be established.
