When the nâdîs become free from impurities, and there appear the outward signs of success, such as lean body and glowing colour, then one should feel certain of success. 19.
By removing the impurities, the air can be restrained, according to one's wish and the appetite is increased, the divine sound is awakened, and the body becomes healthy. 20.
If there be excess of fat or phlegm in the body, the six kinds of kriyâs (duties) should be performed first. But others, not suffering from the excess of these, should not perform them. 21.
The six kinds of duties are: Dhauti, Basti, Neti, Trâtaka, Nauti and Kapâla Bhâti. These are called the six actions.
These six kinds of actions which cleanse the body should be kept secret. They produce extraordinary attributes and are performed with earnestness by the best of Yogîs. 23.
