The Mind is an apartment with 4 rooms: 4 centers: Thinking Mind, Feeling Mind, Sensing Mind and Moving Mind. People unconsciously have their center of gravity in one of these 4 minds.
Man's psychic structure is composed of these 4 centers. These 4 functions only come with the physical body. The art of rising in consciousness is separate consciousness from functions. While Psychic structure has two parts. Higher part and Lower part. The lower part consists of four lower functions. The higher part is the two higher centers, higher Thinking and higher Feeling.
