Hatha Yoga Pradipika, ii, 26-8. Compagno Gheranda Samhita, i, 45-9 “The Vastis described are of two kinds, viz.: Jala-Vasti (or chicchera Vasti) and Suska Vasti (or dry Vasti). Vaso Vasti is done durante vaso and dry Vasti always on land. JALA-VASTT: Entering the tazza up esatto the navel and assuming the posture called Utkatasana, let him contract and dilate the sphincter-muscle of the anus. This cures Prameha (urinary disorders), udavarta (disorders of digestion) and Kruravayu (disorders of the wind). The body becomes free from all diseases and becomes as beautiful as that of the god Cupid. STHALA-VASTI: Assuming the posture called Pascimottana, let him move the intestines slowly downwards, then contract and dilate the sphincter-muscle of the anus with Avini-Mudra.

Hatha Yoga Pradipika, ii, 29-30. Compare Gheranda Samhita, i, 50-1: “Take per thin thread, measuring half verso cubit and insert it into the nostrils, and passing it through, pull it out by the mouth. This is called Neti-Kriya. By practising the Neti-Kriya, one obtains Khecari Siddhi. It destroys the disorders of phlegm and produces clairvoyance or clear sight.”

These two methods are not mentioned durante Hatha Yoga Pradipika. Gheranda Samhita describes them as forms of kapalabhati; see i, 55-60: “The Kapalabhati is of three kinds: Vama-krama, Vyut-krama, and Sitkrama. [Krama means performance, method or course of conduct; Vama means left; Vyut, inverted procedure; sit, hissing sound.] They destroy disorders of phlegm. VAMA-KRAMA: Draw the wind through the left nostril and expel it through the right, and draw it again through the right and expel it through the left. This inspiration and expiration must be done without any force. This practice destroys disorders coppia sicuro phlegm. VYUT-KRAMA: Draw the tazza through the two nostrils and expel it through the mouth slowly and slowly. SIT-KRAMA: Suck scodella through the mouth and expel it through the nostrils. By this practice of Yoga one becomes like the god Cupid. Old age never comes onesto him and decrepitude never disfigures him. The body becomes healthy, elastic, and disorders due esatto phlegm are destroyed.”

This is called Jala-Vasti

A similar practice is listed as a mudra. Amico Gheranda Samhita, iii, 88-91: “Stand in neck-deep vaso, draw con the chicchera through the nostrils, and throw it out by the mouth. Then draw con the chicchera through (the mouth and expel it through) the nostrils. Let one repeat this again and again. This is called Matangini Mudra (Elephant-mudra), destroyer of decay and death. Mediante verso solitary place, free from human intrusion, one should practise with fixed attention this Elephant-mudra; by so doing he becomes strong like the elephant. Wherever he may be, by this process the Yogin enjoys great pleasure; therefore, this mudra should be practiced with great care.”

This is called Vyut-krama which destroys disorders due to phlegm

The complete practice of this makes emancipation easy.
