Vastra Dhauti is one of the six purification techniques of Hatha Yoga called the Shatkarma. Vastra Dhauti is specifically aimed at cleaning the stomach and esophageal tract. In this practice a long strip of moist cotton cloth is swallowed into the stomach. After retaining it for some time, it is pulled out thereby cleaning the stomach.
Steps to do Vastra Dhauti
Sit in the squatting position (or Utkatasana). One may also assume simple sitting position with spine straight (Sukasana), if that is more comfortable.
Take one end of the moist cloth and insert into the mouth. Let the other end of the cloth rest in the bowl.
Hold the cloth near the mouth with your hands and slowly start swallowing the cloth. This may seem difficult in the beginning. For beginners, try swallowing just 1 or 2 feet on the first day. The second day you can increase the length to 3 feet and on the third day to 4 ½ feet and so on. Some may be able to swallow the full length of 20–25 feet on day one, but that depends on the individual capacity.
You can also sip the water from the glass to help you in the swallowing process.
Continue the process till the full length of the cloth is inside. Make sure you leave at least half feet of cloth outside, so that you can pull out the cloth at the end of the practice.
Once you have swallowed the full piece of cloth, you can churn and rotate the stomach from side to side. Those who know the practice of Nauli may also perform gentle Nauli to churn the abdominal muscles.
Keep the cloth inside from few minutes to for maximum of 20 minutes. If you keep it longer, the cloth may end up in the small intestine by the regular movements in the stomach.
Now pull the cloth out of the mouth very slowly. The cloth will be wet with lot of mucus and other sticky substance from the inner lining of the intestinal tract.
Wash and sterilize the cloth to reuse it next time.
