"Being without distraction and of a calm mind, one should practise prāṇāyāma. Even a person who is well-skilled in the practice of the three banḍhas should try always to cognise with a true heart that Principle which should be known and is the cause of all objects and their attributes. Both expiration and inspiration should (be stopped and made to) rest in restraint of breath (alone). He should depend solely on Brahman which is the highest aim of all visibles. (The giving out of) all external objects is said to be rechaka (expiration). The (taking in of the) spiritual knowledge of the Śāsṭras is said to be pūraka (inspiration) and (the keeping to oneself of) such knowledge is said to be kumbhaka (or restraint of breath). He is an emancipated person who practises thus such a chiṭṭa. There is no doubt about it. Through kumbhaka, it (the mind) should be always taken up, and through kumbhaka alone it should be filled up within. It is only through kumbhaka that kumbhaka should be firmly mastered. Within it is Paramaśiva. That (vāyu) which is non-motionless should be shaken again through kaṇtha-muḍrā (throat-posture). Having checked the course of vāyu, having become perfect in the practice of expiration and restraint of breath and having planted evenly on the ground the two hands and the two feet, one should pierce the four seats through vāyu through the three yogas. He should shake Mahāmeru with the (aid of) prakotis (forces) 1 at the mouth of vāyu. The two putas (cavities) being drawn, vāyu throbs quickly. The union of moon, sun and agni should be known on account of nectar. Through the motion of Meru, the ḍevaṭās who stay in the centre of Meru move. At first in his Brahma-granṭhi, there is produced soon a hole (or passage). Then having pierced Brahma-granṭhi, he pierces Vishṇu-granṭhi then he pierces Ruḍra-granṭhi. Then to the yogin comes veḍha 2 (piercing) through his liberation from the impurities of delusion, through the religious ceremonies (performed) in various births, through the grace of gurus and ḍevaṭās and through the practice of yoga.
