ŚODHANA : Ṣ AṬ KARMA
The first, or cleansing, is effected by the six processes
known as the ṣaṭ karma. Of these, the first is Dhauti, or
washing, which is fourfold, or inward washing (antardhauti),
cleansing of the teeth, (danta-dhauti), etc., of
the “heart” (hṛ ddhauti), and of the rectum (mūladhauti).
Antardhauti is also fourfold—namely, vātasāra, by which
air is drawn into the belly and then expelled; vārisāra,
by which the body is filled with water, which is then
evacuated by the anus; vahnisāra, in which the nābigranthi
is made to touch the spinal column (meru): and
bahiṣkṛ ta, in which the belly is by kākinī-mudrā 2 filled
with aif, which is retained half a jāma 3 and then sent
downward. Dantadhauti is fourfold, consisting of the
cleansing of the root of the teeth and tongue, the ears
and the “hollow of the forehead” (kapāla-randhra). By
hṛ ddhauti phlegm and bile are removed. This is done by
a stick (daṇ ḍ a-dhauti) or cloth (vāso-dhauti) pushed into
the throat or swallowed, or by vomiting (vamanadhauti).
Mūladhauti is done to cleanse the exit of the
apānavāyu either with the middle finger and water or
the stalk of a turmeric plant.
Vasti, the second of the satkarma, is twofold and is
either of the dry (śuṣka) or watery (jala) kind. In the
second form the yogī sits in the utkatāsana 4 posture in
1 Gheraṇḍa-Saṃ
hitā, First Upadeśa.
2 Gheraṇḍa-Saṃ
hitā, Third Upadeśa (verse 86).
3 A jāma is three hours.
4 Gheraṇḍa-Saṃ
hitā, Second Upadeśa (verse 23). That is squatting,
resting on the toes, the heels off the ground, and buttocks resting on heels.
