“The Isha Upanishad is the gospel of a divine life in the world and a statement of the conditions under which it is possible and the spirit of its living” writers Sri Aurobindo in one of the commentaries that make up this book. He had a special interest in this Upanishad, and translated and commented on it a number of time before presenting his final interpretation in a terse, 75-page analysis. In the present volume that final translation and analysis are followed by ten earlier commentaries. All of them help us understand “the object of our existence, which is to manifest. The glory of the divine Life and the divine Being.”
