Other times the controlling cycle is also known as the destructive cycle. Vita-vapor is the life force which flows through all the yin and yang organs. Deficiency of vita-vapor in any organ means that organ is out of balance. Each element has specific meridian for the flow of vita-vapor. For example, if the heart is imbalanced the heart will adversely affect the lungs, and the imbalanced vita-vapor within the small intestine will adversely affect the large intestine.
Imbalance also means either too yin or too yang.
Darr Moo exercises are designed for alleviation of the imbalanced function of human organs, to remove tension, stress, anger and anxiety, which can inhibit the absorption of necessary nutrients. The arrows indicate the direction of inhibition of one Element by the other in a cycle. The universe maintains its balance also through the yin and yang balance of the vita-vapor. Since human body is a microcosm of the universe, it achieves the mental and physical harmony in the same way. The vita-vapor has four directions, ascending and descending for transformation, entering and leaving for development.
