Naradaparivrajaka Upanishad

[4] The Upanishad, which is presented in nine chapters, opens by describing the tale of Nārada, a Vedic sage revered in numerous texts of the Hindu tradition, who deeply meditates in mythical Naimisha Forest mentioned in the epic Mahabharata.

[18][16] Nārada, asserts the text, tells them that a man should first complete the samskaraas (rites of passage in life), complete studies in Brahmacharya from a Guru (teacher) he reverentially loves for twelve years, then be a householder or Grihastha for twenty five years, be a Vanaprastha or retired forest hermit for another twenty five, then finally renounce if he has no more attachments, is calm, free from enmity against anyone.

[23] The text asserts the view also found in much older Sannyasa Upanishad, that a sannyasi does not do "social rituals, divine worship, propitiatory rites and such practices", he is beyond pilgrimages, vows, injunctions and temporal actions, states Olivelle.

[25] Verses 193–194 of the text assert that the renouncer lives in his own self, and therefore transcends all social classes and orders of life, for him no laws or restrictions or prohibitions apply.

[27] The text is also notable for its description of how anyone in mortal danger may renounce,[28] as well as describing the life of renunciation as the highest Yoga, as that of aloof self-content person who is a meditator of Brahman and Vedanta philosophy.
