How to Correctly and Properly Guide the Manas?

When the mind consciousness studies the dharma of suffering, emptiness, impermanence, and non-self of the world of the five aggregates, contemplation will permeate and guide the manas, so that it no longer grasps at and clings to these arising-and-ceasing, impermanent dharmas. When studying any dharma principles, one must contemplate them and permeate the manas; once the manas understands the dharma principles, its grasping and attachment will gradually diminish. Correct contemplative practice (vipaśyanā-caryā) that accords with reason and accords with the Dharma is the effective way to guide the manas.
