It is one of the 16 Upanishads attached to the Samaveda. It is classified as a Sanyassa Upanishad. It deals with the cultural phenomenon of a Sanyasi (Hindu monk), a practitioner of Sannyasa or renunciation. The Upanishad also outlines the character and lifestyle of a Paramahamsa, the monk who has achieved the highest state of spirituality. The text is told as a sermon from the god Prajapati (identified with Bramha in some commentaries) to the sage Aruni, who gives his name to this Upanishad.
