of oneness and one feels one's identity with it. Verses 10.6–15 suggest that one must concentrate on self as the supreme self, oneness with Brahman in everything, and this process of attachment of one's individual self to the supreme self leads to oneness and liberation. Verses 10.19–23 advise that those who seek liberation in life or after death, should do yoga and reach the stage of Samadhi wherein one fixes one's mind on the supreme self. This is recommended for those in their advanced years and seekers of inner liberation and peace. Yajnavalkya suggests to Gargi that she should meditate on the self in her through yoga, and thus attain nirvana. Dharma of a yogin, Astanga yoga Gargi, in chapter 11 asks Yajnavalkya whether a yogin in the state of Samadhi needs to perform Vedic duties.

With the vital air under control through the yoga, the yogin realizes signs of progress such as a relaxed state of body, manifested divine sound or nada inside. Verses 12.10–14 state that this Kundalini fire is situated in the navel, and should be meditated upon by breathing exercises. This warms up the Kundalini, awakening her, and the warmth glows through the entire body, and at this stage the yogin must draw the breath above the navel. The Yoga Yagnavalkya explains that warm air inhaled passes to the Brahmarandhra via the navel which helps in curing diseases. When hot air is retained in the heart it is the stage when it makes entry into the Sahasrara Chakra, the thousand petaled lotus, that then emerges in an inverted form. When the vital air is held in the abode of Brahman
