Levels of Doctrinal Habituation

Learning and practice are divided into two levels: initially at the superficial level of consciousness, and ultimately reaching the deep level of the manas (mind root). The study of any theoretical knowledge first begins with consciousness, and at the outset, it does not yet reach the manas. While learning, consciousness simultaneously permeates the manas. Once this permeation succeeds, the theoretical knowledge is mastered, transforming into one's own genuine insights and becoming one's own learning and skill. This can be applied anytime, anywhere, without obstruction or forgetfulness. Only knowledge grasped solely by consciousness is forgotten, because it is acquired—belonging to others, not oneself. What belongs to oneself is never forgotten and does not require deliberate memorization; it arises naturally when needed. This is called the spontaneous manifestation of the self-mind, not mere parroting. In the practice and realization of the Buddha Dharma, it is also described as the spontaneous manifestation of the self-nature.
