Among the oldest of India's spiritual texts, the Upanishads are records of intensive question-and-answer sessions given by illumined sages to their students in ashrams, at family gatherings, in a royal court, and in the kingdom of Death. The sages share flashes of insight, extraordinary visions, the results of their investigation into consciousness itself. The Upanishads have puzzled and inspired wisdom seekers from Yeats to Schopenhauer. In this best-selling translation, Eknath Easwaran makes these challenging texts more accessible by selecting the passages most relevant to readers seeking timeless truths today. This book includes an overview of the cultural and historical setting, with chapter introductions, notes, and a Sanskrit glossary. But it is Easwaran's understanding of the wisdom of the Upanishads that makes this edition truly outstanding. Each sage, each Upanishad, appeals in a different way to the reader's head and heart. For Easwaran, the Upanishads are part of India's precious legacy, not just to Hinduism but to humanity, and in that spirit they are offered here.
