Both the eradication of the view of self and enlightenment (seeing the mind) are realized by the manas.

The realization of fruition through the eradication of the view of self (satkāya-dṛṣṭi-prahāṇa) is the manas's acknowledgment that the five aggregates are not the self. At the time of enlightenment and seeing the mind, the manas not only acknowledges that the five aggregates are illusory and not the true self, but also realizes the tathāgatagarbha, knowing that the tathāgatagarbha is the true self and that the manas itself is not the true one. At this point, the manas has found the master, but the afflictions and habitual tendencies still remain, though they can be somewhat lighter. After the manas knows that the tathāgatagarbha is the true self, and that all dharmas are manifested by the tathāgatagarbha and are all the functions and operations of the tathāgatagarbha, it gradually ceases to appropriate the functions and operations of the tathāgatagarbha as its own, and the grasping at self gradually becomes lighter. Thereafter, one can not only eradicate the grasping at self but also eradicate the grasping at dharmas; when both graspings are completely eradicated, one perfectly attains buddhahood.
