In this book I have given the Vedic theory of Life which incorporates consciousness as the primary characteristic of life. I have given a scientific analysis of what life is and described the characteristics of both Life and Matter and their points of similarity and distinction. I have discussed evolution and then described an alternate theory namely the Vedic theory of evolution of consciousness as opposed to Darwin's theory of evolution of species. The theory of evolution of consciousness is based on creation of various species by God so as to accommodate the varied desires of an infinite number of living beings. The Vedic theory of evolution of consciousness marks the dawning of a new era in which consciousness will come to be incorporated as an essential item in our scientific theories about life and its origin.Topics covered are:* What is Life? - Life vs. Matter* Proof of God's existence* Evolution* Evolution of consciousness* Moral implicationsWhat is Life? Is life simply a product of or combination of material elements? How can matter which is devoid of consciousness give rise to life which is conscious? These questions are the basis of a scientific analysis of life and the debate: creation vs. evolution. I have also discussed in this book the moral and spiritual ramifications of these theories. These fundamental theories of life have far reaching moral consequences on the course of development and well being of mankind. The significance of these theories cannot be over estimated as these are fundamental theories of life. The course of mankind depends on its thinking as regards life and thinking of mankind is greatly influenced by what is taught in schools about life and its origin. Hence this discussion: creation vs. evolution is very important. By teaching Darwin's theory of evolution mankind is on the perilous course of a godless society where the moral fabric of society is being eroded.
