By Swami Harshananda
Cleansing the body is an important aspect of Haṭhayoga. Such processes are known by the term ‘ṣaṭkarma’, one of which is dhauti. Of the four kinds of dhauti, mulaśodhana is also the one. It is the purification of the rectum and the large intestines using a stalk of the root of turmeric or the middle finger of the hand. It should be done only under the guidance of an expert.
