IV. Pranayama (Breath Control)
Pranayama is the measuring, control, and directing of the breath. Pranayama controls the energy (prana) within the organism, in order to restore and maintain health and to promote evolution. When the in-flowing breath is neutralized or joined with the out-flowing breath, then perfect relaxation and balance of body activities are realized. In yoga, we are concerned with balancing the flows of vital forces, then directing them inward to the chakra system and upward to the crown chakra.
Pranayama, or breathing technique, is very important in yoga. It goes hand in hand with the asana or pose. In the Yoga Sutra, the practices of pranayama and asana are considered to be the highest form of purification and self discipline for the mind and the body, respectively. The practices produce the actual physical sensation of heat, called tapas, or the inner fire of purification. It is taught that this heat is part of the process of purifying the nadis, or subtle nerve channels of the body. This allows a more healthful state to be experienced and allows the mind to become more calm.x As the yogi follows the proper rhythmic patterns of slow deep breathing "the patterns strengthen the respiratory system, soothe the nervous system and reduce craving. As desires and cravings diminish, the mind is set free and becomes a fit vehicle for concentration."
