Subtler than the food sheath, the vital air sheath controls and regulates the physical body by the air we breathe. Specifically, the vital air sheath manages five physiological faculties - perception (through senses), excretion, digestion, circulation, and thinking. Breath serves as a bridge between the body and mind. Stressful conditions can result in inefficient breathing but specific, purposeful breathing techniques help calm the mind and emotions.
Breath is the essence of life. Focusing on practices that enhance our breath strengthens our relationship between the mind and body.
