This book attempts to let the universal Upanisadic knowledge and experience of Divinity and Reality emerge from the original texts and make it accessible to a broader western-oriented audience. The book is in text-commentary format and uses the method of parallel texts. The present book emphasizes the fact that many of the Upanisadic vidyas use the Brahmana knowledge of Divinity as a starting point for developing knowledge of Atman/Brahman.
