Purification (Shaucha) is a central aim of all the yogic practices and is the first principle of self-discipline (Niyama) in Patanjali’s eight-limbed (Ashtanga) approach. We are constantly exposed to toxins from our air, water, cleaning products, processed foods and emotional toxins induced by stress. Yoga purifies the body and mind by stimulating and purifying the lymphatic system, circulatory system, respiratory system, by bringing health to our digestive tract, calming the mind and stimulating the internal organs.
