Another channel is called Suṣumṇā, situated in soma, fire, and the mind. / In this body endowed with elements, it is situated in the Kūrmāra wind,
attached to the ankle and the palm of the hand, contracting and extending. / Joined with the Samāna and Vyāna [winds], it satisfies blood and flesh.
The other wind which is Udāna and that which is called Kūrmāra, / both of those are established in balance in the channel tied to the navel.
