Book The Upanishads by Sri Aurobindo contains his final translations of and commentaries on the Isha and Kena, his final translations of the Mundaka and Katha Upanishads, and a commentary on part of the Taittiriya Upanishad. Upanishads are the ancient treatises on spiritual truths as envisioned by the seers, sages and rishis of the civilization of India.
They are preceded by a chapter on the Upanishads from A Defence of Indian Culture. These works represent Sri Aurobindo‘s Upanishadic interpretation in its most mature and finished form. All were written after he settled in Pondicherry in 1910. Translations and commentaries written before that year, or left incomplete by the author, have not been included in this volume. They are available in other publications.
