成唯識論述記 5.319

5.319

述曰：下引證也。五十五說不信等至皆相應故，名有六也。此師意說，一切染心此之六種皆相應故。不信、懈怠、放逸，三種行相不違，如前師說，實遍染心。忘念等三，前來未解，故今應釋。

The Commentary states: Below, it cites proof. Fascicle 55 states that from non-faith onward... because all are associated, they are called six. This master's intention is that in all defiled cittas, these six kinds are all associated. For non-faith, laziness, and heedlessness, their three ākāras are non-contradictory, and as the previous master said, they truly pervade defiled citta. The three such as forgetfulness have not been explained before, so they should now be explained.
