The author of this book has written various spiritual cum scientific advanced-level books. He has devoted his entire life to the search for Brahman. Brahman doesn't mean exactly as God. This book is his latest research work based on his entire life experiences. He has an extraordinary ability to synthesize the latest scientific discoveries (mainly cosmological discoveries by the Hubble Telescope) and the spiritual revelation/discoveries by great self-realized saints mainly Sri Adi-Shankaracharya. Sri Dharam Vir Mangla is a philosopher-scientist and master of his subjects. Strangely, none after Sri Adi-Shankaracharya has ever tried to justify the latest scientific discoveries with the great truth Sri Adi Shankaracharya revealed to humanity about 1300 years ago. The concept of Brahman is indeed most difficult to understand by ordinary humans. To understand Brahman you need both the knowledge of Sciences and the Scriptures mainly Vedas, Upanishad, and Sri Adi-Shankaracharya. This book is a spiritual and scientific advanced-level book and is mainly concerned with understanding ultimately the absolute reality and truth known as Brahman. By this book, it is hoped that the readers will understand Brahman better. The book explains what scientists are unable to understand like Dark matter, Dark-energies, the entire space, the structure of the universe known, the Theory of Relativity which has changed now, Stephen Hacking's false theories, the end of the universe, how the universe was originated, etc. and the most mysterious expansion of the universe with more than velocity of light, etc. The readers will be enthralled by reading this book and will start their spiritual journey to know Brahman further. The question arises who is expanding the entire observable and unobservable universe with more than the velocity of light and with great acceleration also? Who has created our universe and given us human birth on this earth? What are our dreams and various states of Mind? What is our relationship with Brahman? Are we all Brahman? Is everything Brahman? Is it true? The answer to such unlimited hundreds of questions the author has tried to give in this small book. For detailed knowledge, the author has written other books. The readers will be enthralled by reading this book and will start their spiritual journey to know Brahman further.
