The Hierarchy of Theoretical Perfuming

Learning and cultivation occur at two levels: initially at the shallow level of consciousness, and ultimately reaching the profound level of the mind root. The study of any theoretical knowledge begins with consciousness; initially, it does not yet reach the mind root. As consciousness learns, it simultaneously permeates the mind root. Once this permeation succeeds, the theoretical knowledge is mastered, transforming into one's own genuine insights and becoming personal learning and skill. This can be applied anytime, anywhere, without obstruction or forgetfulness. Only knowledge grasped by consciousness can be forgotten, since it is acquired, belonging to others rather than oneself. What belongs to oneself cannot be forgotten, nor does it require deliberate memorization—it is readily available when needed. This is called "flowing from one's own mind," not parrot-like imitation. In the practice and realization of the Dharma, some also describe this as "flowing from the self-nature."
