The
Nirvana Upanishad is written in
Sutra-style. A
Sutra means "string, thread", and in Indian literary traditions, it also refers to an
aphorism or a collection of
aphorisms in the form of a condensed manual or text. This Upanishad deals with
Vedanta philosophy. The aphoristic style implies that the text can be interpreted with multiple meanings, is full of metaphors and allegories, and its sutras implicitly refer to Hindu scriptures. "The sky is his belief" in its third sutra for example, states
Patrick Olivelle, is a metaphor for consciousness, spanning everything visible yet indivisible; it also means that the
sannyasi is not enslaved to any specific doctrine but instead follows his own consciousness, his own conception of the absolute. The text asserts that the life of the
sannyasi is of reflection, not rituals. Jnana-kanda (knowledge section of the Vedas) is the scripture of the
sannyasi, states the Upanishad, and not the section on Karma-kanda (rituals section of the Vedas). He is marked by fearlessness, fortitude, equanimity, a conduct that is both respectful of others and his own wishes, he does not revile others nor find faults in others, states the Upanishad. The verse 36–37 of the text asserts a position reverse of the Sunyavada of
Buddhism, states Olivelle, where the Hindu
sannyasi does not accept void-emptiness as ultimate reality, but believes Atman-Brahman as the ultimate reality. The primordial Brahman, states sutra 40 of the text, is self-knowledge for the renouncer. The
sannyasi finds home when he is in union with truth and perfection, states sutra 38 of the text. Self-knowledge is his journey and destination. His state is of an entranced mind, solitude his monastery. He is virtuous, he knows no fear, no delusions, no grief, no anger, no selfishness, no egotism. He contemplates on the true nature, silence is his mantra, he conducts himself as he pleases, his own nature is his liberation, translates Olivelle. ==Reception==
