(Śauca): “Purity,” the first niyama (moral discipline) listed in the Yoga Sutras of Patanjali. Yogis see the body as the vehicle or temple of the soul. Thus, it is very important to have a healthy, clean body so the soul’s purpose can be fulfilled. The physical body can be purified through practicing asanas and pranayama, maintaining a healthy diet, bathing regularly, doing physical exercise, and by practicing various dhautis (cleanses for the internal organs and systems of the body). An aspirant on the yogic path should also cultivate purity of mind, relinquishing negative mental tendencies such as pride, anger, jealousy, dishonesty, judgment, etc. Read more about the niyama here.
