Shatkarma

The shatkarmas (Sanskrit: षटकर्म ṣaṭkarma, literally six actions), also known as shatkriyas,[2] are a set of Hatha yoga purifications of the body, to prepare for the main work of yoga towards moksha (liberation).

These practices, outlined by Svatmarama in the Haṭha Yoga Pradīpikā as kriya, are Netī, Dhautī, Naulī, Basti, Kapālabhātī, and Trāṭaka.

[2][3][4] The Haṭha Ratnavali mentions two additional purifications, Cakri and Gajakarani, criticising the Hatha Yoga Pradipika for only describing the other six.

[1] The shatkarmas are six (or more) preliminary purifications described in the Hatha Yoga Pradipika and later texts.

Their purpose is to remove "gross impurities", cure a range of diseases, and prepare the body for pranayama, trapping the breath so as to force the vital energy prana into the central sushumna channel, allowing kundalini to rise, and so to attain moksha, liberation.

The Shatkarmas are six preliminary purifications used in traditional hatha yoga . [ 1 ]
