This book is an introduction on the formation of this Universe. Who is the creator of this world, this Earth, Sun, moon, Stars, water etc. and the life on this Earth. Is it all an auto process of nature or is there any super power to create and control it? I have written this all in a simple Hindi language and in an interesting way. The matter is stated in such a way that any body can understand it. The chapters in book deal with the Santana Supreme Power (God) Bhawan Vishnu and His 24 and 10 recreation (Avtar) life stories on Earth. Certain are elaborated and others are in short cuts as per the required subject matters. I am sure that this book will of great interest, knowledge and useful for our present and future generations. With best wishes and good luck to all readers.
