This book is the beauty of nature is unbelievable. It has no definite start as well a predefined end. Each everything is systematic and following some basic laws. Everything is changing with the passage time. When we look upward we see that sun, moon are moving around, starts are in the sky twinkling. It is obvious that a person is forced to think that which force and what force has maintained the whole system. How these are bound witheach other. Let us first of all try to know the meaning of Force.
