Samnyasa Upanishads: Hindu Scriptures on Asceticism and Renunciation c6.s2.64

c6.s2.64

Placing both his hands on the spot between his anus and genitals, and gently biting³¹ his tongue extended out to the size of a barley corn, let him engage in the control of breathing.³²

Eyes open the size of a bean and fixed on ears and brows, [*24*] let him keep his nose and his ears from contact with odors and sounds.

Through this exercise whose habit comes from former lives, he then attains the blessed state, where abides Brahman, the final end.

Then, fixing the heart on penance by these means, breath breaks the crown, rises up from the body, and reaches the Imperishable.³³
