Shudhi Kriyas are natural cleansing procedures which help in internal purification. ‘Neti’, ‘Dhouti’ and ‘Nauli’ are the ‘Kriyas’ used by our yoga gurus to purify and reinvigorate the vital organs of the body. ‘Neti’ is the cleansing of the nasal passages. ‘Neti’ alleviates respiratory diseases like sinusitis, allergy and asthma and throat infections. It has a soothing effect on the brain, eyes, and ears. ‘Dhouti’ is the cleansing of the alimentary canal. ‘Dhouti’ is performed to remove undigested food from the stomach and thus prevent the accumulation of toxins in the body.
