Swami Nikhilananda's English translation of two of the major Upanishads - Taittiriya and Chhandogya - offers a scholarly, yet readable version of these sacred texts of ancient India. The Upanishads form the foundation of the Hindu religion and describe the ultimate objective of life - the liberation of the soul from the bondage of the phenomenal world. Swami Nikhilananda's clear and insightful writing combined with notes and explanation based on the commentary of Sankaracharya, the great eighth-century philosopher and mystic of India, will help the spiritual seeker delve into the meaning of these spiritual treasures. This fourth volume also contains introductions to the two Upanishads describing rituals and contemplative worship as steps leading to the knowledge of God
