हठयोग प्रदीपिका (योगी स्वात्माराम - ज्योत्स्ना टीका सहित सटीक)

66 HAṬHAYOGAPRADĪPIKĀ [activity of] Prāṇa there is [that of the] mind, where there is [activity of] the mind, there is [that of] Prāṇa. 25. If one is suspended, the other is set at rest. If one acts, the other [too] acts. If they are not quietened, all the senses are active; if they are controlled the state of liberation is attained. 26. Mercury and mind are unsteady by nature. If mercury and mind are bound [i.e. stabilized], what is impossible of attainment on this earth? 27. O Pārvati! Mercury, as also Prāṇa, when immobilized, destroy diseases; when [themselves] dead [i.e. inactive], they give life; when bound, they enable [persons] to rise in the air. Mercury is made solid and inactive by the use of herbs; and the Prāṇa is made immobile when absorbed in the Brahmarandhra by means of Kumbhaka. When mercury is bound (by a certain process) and reduced to the form of a pill, it is called gahanaguṭikā, and by putting it in the mouth, one can rise in the air. In the same manner, Prāṇa, when held in the centre between the two eyebrows, enables one to rise in the air. The Gorakṣaśataka says: ‘Between the eye- brows there appears a round spot, black as a ball of collyrium. It is of the essence of Vāyu, and its presiding deity is Īśvara. Restraining the Prāṇa in this Cakra along with the mind for two hours gives the power of rising in the air to a Yogin.’ 28. When the mind is steady, the Prāṇa is stable, and hence there is stability of semen. There is always strength when the semen is stable, and it gives the body stability. 29. The mind is the lord of the organs of sense; the Prāṇa is the lord of the mind; absorption (laya)
