Liberation Is Solving the Problem of the Manas.

Fearing one's own disappearance when entering meditative concentration (samādhi), fearing one cannot come back—these are all fears of the manas. It requires the mind consciousness to persuade the manas not to cling to its own body of the five aggregates (pañca-skandha), for the body of the five aggregates is not real. Therefore, the eradication of the view of self (satkāya-dṛṣṭi-prahāṇa) must be accomplished by the manas; severing afflictions must be done by the manas severing afflictions; severing ignorance requires the manas to sever ignorance. All afflictions belong to the manas, and liberation is precisely the resolution of the manas's problems.

How many examples illustrate this point: when the power of meditative concentration is insufficient and the power of wisdom is insufficient, one simply cannot recognize this. That manas is so dull and stupid, yet it still treasures the mind consciousness—when the manas itself has caught fire, it doesn't even know it, and instead goes to put out the fire of the mind consciousness; the family estate has all burned down, yet it still wanders around the periphery. What kind of wisdom is that?
