The other day when I practiced vastra dhauti, I noticed something very interesting. As I started to draw out the cloth, it felt like it was being gripped from inside. When I kept a constant, light pull, it didn’t slide out smoothly. Instead, it came out in small pulses, as if something inside was releasing it little by little.
The Haṭha Yoga Pradīpikā (2.24) and Gheraṇḍa Saṁhitā (1.16–18) describe Vastra Dhauti as a practice where a moist, clean strip of cloth is swallowed and later withdrawn, purifying the stomach. The texts say the stomach “grasps and pulls it in”, which should not be taken literally; rather, once throat resistance is overcome, the natural peristaltic movement of the esophagus and stomach muscles carries the cloth inward, giving the yogi the feeling that the stomach itself is drawing it inside. It purifies the stomach, removes excess bile and phlegm, and prepares the yogi for subtler practices.
That made me wonder: was the cloth stuck in my stomach? Or was some sphincter muscle holding it?
After thinking over it, I realized the esophagus has two main sphincters. One is the cardiac (lower esophageal) sphincter, which sits just above the stomach, and the other is the pyloric sphincter, which sits at the stomach’s exit into the intestine. The pulsative grip I felt was most likely from the cardiac sphincter. This sphincter naturally prevents food or foreign objects from falling freely into the stomach, so the entire cloth cannot simply slip down and get trapped.
That discovery was a relief. It meant that if one end of the vastra is held in the hand, even a beginner should be able to withdraw it safely, though slowly and with patience. The pulsating contractions and the irritation from the cloth itself help in gradually pushing it upward.
Then another thought struck me: if my cardiac sphincter can grip the vastra this strongly, does it mean my sphincter is not weak? I’ve been dealing with GERD (acid reflux), and one common explanation is that the lower esophageal sphincter gets weak. But maybe in my case, that isn’t the whole story. Perhaps there are other reasons for my reflux.
This is where the question of food sensitivity came up. I wondered if gluten sensitivity might be a hidden factor, mainly in ankylosing spondyloarthritis like me. Gluten can irritate the gut lining in some people and worsen reflux or bloating, even when the sphincter itself is working fine.
But then I noticed something else: even when I ate jwar (sorghum) roti, which is gluten-free, it felt hard to digest. Although I found relief with it when well cooked, thin and in small to moderate quantity. This made me realize that digestion is not just about gluten. Foods like jwar, bajra, and chana are heavy, high in fiber, and too much can sit in the stomach longer, which can sometimes worsens reflux.
I considered mixing grains: jwar + bajra + chana multigrain roti. This could balance heaviness with variety, but it may still feel dense if digestion is already weak. On the other hand, lighter options like oats + kutki (little millet) seem easier on the system.
Yet, I have a deep habit of eating roti every day. It’s cultural, emotional, and satisfying. So the challenge is not to quit roti, but to find the grain combination that gives me both digestibility and comfort.
From this whole journey, my learnings are:
- The body has natural safety mechanisms (like the sphincter grip in dhauti).
- GERD is not always about a weak sphincter; food type and sensitivity matter a lot.
- Heavy gluten-free grains can also be tough, so light mixes may be better.
- Habits like roti can be kept, but with smart substitutions.
In the end, the practice of dhauti not only helped me cleanse but also gave me a direct insight into how my sphincter works. That, combined with my experiments with roti and grains, is slowly teaching me the personal balance I need for both yoga practice and digestive health.
I got help in meditative Dhyana, relief from GERD, and an improvement in personality through it. I felt I had come to know enough of the interior of my body. Dhouti Vastra was like a narrow clinical gauze bandage, about 1.5 feet in length. The throat resists it and propels it out with coughing; it only enters the stomach if enough normal saline water is drunk along with it. The outer end should never be swallowed, otherwise it may be lost inside and surgery could be required to remove it. Therefore, this is a serious practice and should be done cautiously, under the guidance of an expert.
