In answering a question to the young Rama, Vasishtha is reminded of his encounter with Muni Kag Bhusunda, who resides in the Sumeru Hills in a kalpa tree. Upon questioning, Kag Bhusunda explains how he has both form and immortality, through both creation and dissolution, again and again, and again. Kag Bhusunda explains the process of kumbhaka, stability in prana and apana, management of the breath process.
