The Upanishads are records of the deepest spiritual experiences of the ancient Indian Rishis of that age. It is here that one gets a glimpse of the workings of the minds of the great seers and thinkers of ancient India. It is from here that the entire systems of Indian philosophy and religion and spirituality have drawn their inspiration and the energy for their growth and enrichment. The Upanishads represent the true Indian spirit in not only religion, philosophy and spirituality but they are also the fountain-head of all Indian art, poetry and literature.
There are several commentaries, both ancient and modern, by Indians and scholars from the West. Among them the writings of Sri Aurobindo on the Upanishads occupy a special place as they are based directly on intuitive and spiritual experiences, and are yet presented in a manner suitable to the modern rational mind.
We present here the major Upanishads in the light of Sri Aurobindo, which may be useful for the spiritual seeker, the scholar of religion and philosophy, and the student interested in Indias spiritual tradition, her ancient and rich culture. It will be of special benefit to the youth who want to imbibe the values contained in the Upanishads and to build a new India in the future.
