Two things are surprising about the life, its mysterious nature & our will to conquer it. Whatever we try to do it's never guaranteed that we will achieve it & in fact it is never completely achieved. Mystery of the life lies in its uncertainty & it's always new doesn't matter how much we try & whatever the conditions are, we always believe that we can conquer the nature.This book tries to explain this uncertain nature & exact role of the human's will in the life. The conclusions in this book are not new, what's new is the approach & presentations so that a scientific as well as a common person can understand & accept it. There are number of examples from the occurrences of the life as well as there are pictorial representation & scientific correlations in an attempt to draw a logical & conceptual understanding about the things.The presence of ego or self or will itself signifies the imperfection about the life & complements the uncertain & infinite nature of the life. To attain the perfection fall of ego is necessary. Ego is something that links us from the nature in the life. By saying us, I mean the supreme knowledge that guides us to a true path about the life.The adversity of the life is we recognize ourselves by our ego, only & there is the reason as well behind it. Ego is our self-imposition, a false impression that we are the master of the nature & the destiny while the nature is something beyond our understanding & the control & supreme power is something which directs us.In the 2nd edition, I have just corrected some grammatical mistakes & improved some of the matters a bit more.
