The Shatkarmas are the six purification techniques mentioned in Hatha Yoga Pradeepika. Shatkarma makes the body clean, strong, free of diseases. It removes toxins and improves concentration. It improves the flow of prana into the organs. The six techniques are – Dhauti, Bhasti, Neti, Trataka, Nauli and Kapalabhati. Some of the techniques have more than one variation. Shatkarma techniques should be learned from an experienced yoga master. Netī refers to nasal wash. This is the practice of using a neti pot to cleanse the nasal passages. A basic neti wash consists of purified water and non-iodized salt, to create a gentle saline solution. A demonstration of this practice is available through the website of the Himalayan Institute. Kapālabhātī refers to skull polishing, and is a pranayama (breathing) practice intended to energize and balance the nadis, and the chakras. Specifically, it is a sharp, short outbreath, followed by a relaxation of the core that allows the body to inhale on its own. Naulī refers to intestinal cleansing. The practitioner stands with the feet about hip width apart, hands on knees, and body at about a 45 degree angle. The core is rotated internally by moving the abdominal muscles alternately in a clock-wise, then counterclock-wise direction.
