Learning and practice are divided into two levels: initially at the shallow level of consciousness, and ultimately reaching the deep level of the mental faculty. The study of any theoretical knowledge begins with consciousness, which cannot initially access the mental faculty. While consciousness learns, it simultaneously influences the mental faculty. Once this influence succeeds, the theoretical knowledge is mastered, transforming into one's genuine insights and wisdom, becoming one's own learning and skill. It can be applied freely at any time and place without obstruction, nor will it be forgotten. Only knowledge grasped by consciousness can be forgotten, as it is acquired from others and does not truly belong to oneself. What belongs to oneself will not be forgotten and does not require deliberate memorization; it is readily available when needed. This is called "emanating from the heart," not mere parroting. In the practice and realization of Buddhism, it is also described as "emanating from the innate nature."
