There are two kinds of energy in the body: warm fire energy and cold water energy. When the body is in balance and optimum health is achieved, the water energy is located in the head and the fire energy is maintained in the abdomen. This state is called "Su-Seung-Hwa-Kang." "Su" means "water," "Seung" means "go up," "Hwa" means "fire," and "Kang" means "come down." "Su-Seung-Hwa-Kang" expresses the universal principle that water energy must go up and fire energy must come down.

"Su-Seung-Hwa-Kang" is universal principle for the life activity in both nature and the human body. In the human body, the water energy is created in the kidneys and the fire energy is produced in the heart. When the water energy moves up through the Doc-Mak (Governor Meridian Channel) located in the middle of the back, the brain feels fresh and cool. The fire energy passing through the Im-Mak (Conception Meridian Channel) located in the middle of the chest down into the abdomen keeps the intestines warm.
