The universe is the Creation and Manifestation of Brahman the ultimate reality. The universe is not different from God (Brahman) and is the physical body of God. Since time immemorial both the yogis and the scientists have been busy in searching for this Ultimate Truth and the path to the salvation of the soul. As the ultimate truth is one and can never be contradictory to any scientific or spiritual system, the author decided to synthesize both and remove the existing differences and misconceptions between the two. This book is an effort for the same. The main aim of the book is to understand better our relation with the universe & God. I have tried my best not to twist any spiritual, scientific, or historical fact to prove my point. To an ordinary man the universe around him looks real in every sense. But all the Holy Scriptures and great saints have declared the universe as Unreal, a Dream and a Thought in the Mind of God. We are confused and want to know the truth. The Maya of God and the limitations of our sense organs are the biggest hindrance in knowing the absolute truth. This book is an attempt to answer this great mystery. This book is a rare masterpiece and a rare attempt of the author to synthesize the Scriptures, God, and the latest scientific research. Everything in the universe is most mysterious and the whole of humanity is busy solving the mysteries. But the more we learn, the more we are confused and exposed to new mysteries beyond the human mind. Generally, we are proud of our little knowledge and correctness of sense organs. But the book explains how our sense organs are working under the influence of Maya and misleading us from absolute reality. The author has gone deep into the subject to explain, whether the universe is a reality or it is simply a great Dream or a Thought in the mind of God. The book explains the unreality of the universe. The greatest puzzle 'Who Am I' is scientifically explained in a systematic manner. The book explains how we can know our ego 'I'? The subtle subjects like Dreams, Death, God, and Self-Realization are discussed deeply in a scientific manner. The concept of structure, origin, destruction, past, present and future of the universe, both as per Vedas and the latest space research is thoroughly discussed and explained by the author.
