Levels of Permeation Through Theory

Learning and cultivation occur at two levels: initially at the shallow level of the mind consciousness, and only at the end can one reach the deep level of the manas. In the learning of any kind of theoretical knowledge, it is always the mind consciousness that begins to learn first; at the initial stage it has not yet reached the manas. While the mind consciousness learns, it simultaneously perfumes the manas. When the perfuming succeeds, the theoretical knowledge is mastered and becomes one's own genuine insight, turning into one's own learning and skill, which can be brought into play anytime and anywhere without obstruction, and will not be forgotten. Only knowledge grasped by the mind consciousness can be forgotten, because it is learned, something belonging to others and not one's own. What truly belongs to oneself will never be forgotten, nor does it require deliberate effort to remember and hold onto—it is available whenever needed. This is called the flowing forth from one's own mind, not a parrot mimicking speech. In the realization of the Buddha-dharma, some also call it the flowing forth from one's own nature (self-nature).
