Dissatisfied with ritual and rigid ways of thinking, the sophisticated and the more daring of the thinkers and teachers of the period
withdrew to ashrams in the forests to ponder and meditate over questions of reality, life and its meaning.

Their thought and teachings took the form of the Upanishads, composed in Sanskrit.

The Upanishads are beautiful, bold and are certainly some of the most profound of human thought.This book Whispers from the Forests, Wisdom of the Upanishads on the Self is designed to provide the reader with an intuitive and creative grasp of the thought, the essential ideas, and feel of the Upanishads.
