The book explores the glory of Om in the context of self-realization. This book is a modern commentary of the ancient text Mandukya Upanishad. In all ages, evolved human minds have never ceased to wander about their own Self. Who am I? Why do we exist on earth? What is the purpose of this life and what happens after death? Does God really exist? Such questions have forever haunted seekers in all cultures and religions of the world. In the light of Mandukya Upanishad, this book addresses such questions that hang around the mind of a seeker of Self-realization. The Mandukya Upanishad contains what is perhaps one of the most exemplary analysis of human consciousness and its relation to God. This book is an wonderful exposition on the verses of the Mandukya Upanishad in the light of modern analysis of human consciousness. This is a must for anybody looking for self-realization.
