Death is the Creator of the World, states an ancient Indian text. In fact, the further away we look into the Universe, the remoter we view into the past. And the past is dead. Death is Lust and Hunger. Death is the price we pay for having eaten the fruit from the "tree of Knowledge." Only the Present goes Beyond Immortality and establishes Life without death. This book explores perennial existential questions in a manner accessible to all readers. It offers original thorough translations of four ancient Indian texts, Ganapati, Isa, Mandukya and Katha Upanishads. It contains commentaries, scientific references and comparisons with texts from different religions and philosophies. Notes, illustrations, rational and non-dogmatic interpretations help to understand controversial concepts contained in this book.
