The specific technique: fill the abdomen with air (vāyunā pūritodaraḥ) and produce controlled belches (udgāra). This creates an internal massage of the cardiac/esophageal region, releasing tension and purifying the area.

The phrase “there is no doubt” (na atra saṃśayaḥ) is a seal of textual authority. The author is not speculating; he is transmitting knowledge proven in the tradition.

Although the technique may seem strange, controlled belching is recognized in several traditions as a mechanism for releasing gas and diaphragmatic tension.
