A Word about the Book The universe is the Creation and Manifestation of Brahman the ultimate reality. Universe is not different from God and is the physical body of God. Since time immemorial both the yogis and the scientists are busy in searching this Ultimate Truth and the path for salvation of soul. As the ultimate truth is one and can never be contradictory to any scientific or spiritual system, I 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 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 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 is the biggest hindrance in knowing the absolute truth. This book is an attempt to answer this great mystery. The whole humanity is busy and spending billions of $ to know the real structure, the future, present, past and origin of universe. How it came into existence and what shall be the end of the universe? With the blessings of great saint Sri Amar Jyoti Babaji and the inspiration from Sri Sathya Sai Baba, Sri Mahavtar Babaji and Sri Paramhans Yogananda I was able to complete this book. This book is a rare masterpiece and a rare attempt of the author to synthesize the Scriptures, God and the latest researches in Cosmology. Everything in the universe is most mysterious and the whole humanity is busy in solving the mysteries. But more we learn, more we are confused and exposed to new mysteries beyond 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 the absolute realty. Author has gone deep into the subject to explain, weather 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 researches is thoroughly discussed and explained by the author. This is a most commendable book for the yogis, scientists, teachers and students. Dharam Vir Mangla
