5.24

Regarding 'mutually augmenting': Question: The seventh serves as the basis of defilement for the sixth, augmenting the sixth; how does the sixth consciousness augment the seventh? Answer: There are two meanings: first, increasing; second, not harming. If the sixth consciousness initiates karma that karmically draws the eighth, which serves as the support and object of that [seventh], enabling it to abide in succession, it is called 'augmenting'. When giving rise to sāsrava [states], even though it might not increase the seventh, it does not harm it, and this is also called 'augmenting'. It is not like anāsrava, the arising of which must harm it, which is not called 'increasing'. Just as sleep, although incapable of increasing the eye faculty, does not harm it and is also called 'nourishing'. This should also be understood in the same way.
