हठयोग प्रदीपिका (योगी स्वात्माराम - ज्योत्स्ना टीका सहित सटीक)

28 HAṬHAYOGAPRADĪPIKĀ 32. By Trāṭaka, all diseases of the eyes are removed and sloth, etc. are overcome. It should be carefully kept secret like a golden casket. 33. Then NAULI [is described]: With the shoulders bent down, one should rotate to right and left the stomach with the speed of a fast-circling eddy. This is called Nauli by the Siddha-s. 34. This Nauli, the crown of Haṭha-yoga practice, stimulates the gastric fire if dull, increases the digestive power, produces happiness and destroys all diseases and disorders of the humours. 35. Then KAPĀLABHĀTI [is described]: Perform Recaka (exhalation) and Pūraka (inhalation) rapidly like the bellows of a blacksmith. This is called Kapāla- bhāti, and destroys phlegmatic diseases. 36. Freed from corpulence, phlegmatic disorders, impurities, etc. by [the performance of the above] six acts, one should practise Prāṇāyāma. Then success [in Yoga] is achieved without strain. 37. Some teachers say that all impurities [of the Nāḍi-s] are removed by Prāṇāyāma alone and other acts [the above-mentioned six] are not accepted [by them]. 38. Then GAJAKARAṆĪ [is described]: [Yogin-s] draw up the Apāna to the throat and vomit the sub- stances [food, water, etc.] that are in the stomach. [This act] the gradual practice of which brings all the Nāḍi-s under control is called Gajakaraṇī by those who know Haṭha-yoga.
