Shaucha, or holistic purity of the body, is considered essential for health, happiness and general well-being. External purity is achieved through daily ablutions, while internal purity is cultivated through physical exercises, including asana (postures) and pranayama (breathing techniques).

Shaucha goes beyond purity of body, and includes purity of speech and mind. Anger, hate, prejudice, greed, pride, fear, negative thoughts are a source of impurity of mind. The impurities of the intellect are cleansed through the process of self-examination, or knowledge of self (Adhyatma-Vidya). The mind is purified through mindfulness and meditation on one's intent, feelings, actions and its causes.
