This book is an attempt to integrate the knowledge gained from modern physics, cosmology and biology with some notions in metaphysics concerning being and time. The fragmentation of our knowledge due to the very narrow specialization of modern science led to the abandonment of the search for the meaning of the events along the history of the universe and the Master Plan behind these events. The creation of the universe and the appearance of life on earth and the development of intelligence and consciousness must have some purpose. The author wonders whether these major events are but the revelations of one Being. What are the attributes of this First Being and how may we gain knowledge of Him? these are some of the questions attempted for answers by the author.
