The Yogi should sit in Bindu's seat and close his nostrils, having learned Sushumna and its Bheda (piercing) and letting Vayu go through the middle.
One should join the sphere of peace, Sahasrara or the Sukha-Mandala, after learning Vayu, the above-mentioned Bindu, and the Sattva-Prakriti, as well as the six Chakras.
