It is one of the 19 Sannyasa Upanishads and is one of the 16  Upanishads attached to the Sama Veda. The Kundika Upanishads discuss when and how someone may renounce, and the answers it gives are different than those found in other Upanishads such as the Jabala Upanishad. The text dedicates most of its verses to the lifestyle of the renouncer, and its broad theme centers around renunciation or spiritual enlightenment. The text mentions ancient cultural and religious Hindu traditions. It describes renunciation as a stage of life where a  man lives like a monk yogi, sleeps on the sand and near temples, and remains calm and kind no matter what others do to him while pondering on Vedanta and meditating on  Brahman through Om. A renouncer, states the Kundika Upanishad, should seek to realize the identity of his soul with the universal soul.
