The key to closing the mind lies in the manas. If the manas is handled well, the six consciousnesses will not crave or cling to feeling, perception, formations, and consciousness, and afflictions and attachments can be eliminated. The key to cultivation is the manas; He is the great gate and master switch of all dharmas. Once the manas ceases, all dharmas become tranquil—no affairs, no mind; no mind, no states of realm—nirvāṇa in tranquility.
