"The system of yogic breathing exercises called pranayama is designed to increase and cultivate the quality of the pranic body. When you start to know where you are in your physical body through the alignment of the poses, you will have more freedom to explore the flow of your breath. By shifting to deep, slow, and rhythmic breathing in your yoga practice, you are becoming conscious of and affecting this second kosha. As you increase the amount of oxygen in your body, this pranic body starts to come alive. The coordination of your inhalation and exhalation with the movements of your physical body, as in the Sun Salutations, is one of the ways in which the physical body and breath body become synchronized with the mental body (concentration and awareness)."
