4.8

論。五者能見至能離故　釋曰。此五意中第二轉識。上三細中能見相也。所依動心轉成能見。能污淨心名之為染。第九地中得無礙智。善知眾生心行稠林自在無礙。名心自在。有礙能緣此永不起故。云心自在地能離也。然無礙智略有四廣有四十。如餘處說。

Treatise: "Fifth, the capable of seeing […] can leave it behind." / Commentary: Among the five intents, this is the second, evolving consciousness. Among the three subtle marks above, it is the characteristic of manifestation. The stirred mind upon which it relies transforms into active seeing; defiling the pure mind, it is called a defilement. In the ninth bhūmi, one attains unhindered cognition; skillfully knowing the dense thicket of sentient beings' mental conduct, free and unhindered, it is called mastery over mind. Hindered active conditioning never arises again from here; thus it is said that "at the ground of mastery over mind, one can leave it behind." Unhindered cognition is briefly fourfold, and in extensive form, fortyfold, as explained elsewhere.
