4.8

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.
