This book discusses the reality of human being by pointing out some of the very fundamental issues that remain hidden from the eyes of the modern and post-modern western thought. By elaborating Mulla Sadra’s concept of Soul’s origination from the body and its survival through the Spirit, this book explains how the human soul develops stage by stage in a gradual manner from a vegetative body in the womb. By using Mulla Sadra’s principles of causality, this book shows how God and his Angels create man and other species on the Earth without denying Darwin’s evolutionary theory. In this reference, the role of metaphysical worlds in actualizing human knowledge is also discussed. This book also shows how the human life is a journey back towards its origin i.e. towards God and how this journey would continue even after death. In this reference, this book also explains the principles on the basis of which human soul would continue its life in the post-humus world. This book also clarifies the benefits of focusing onto the self and how this focus may lead to the realization of the Eternal Self of God. In this way, it shows how it is not impossible to experience the post-humus conditions even before death. It also specifies what kind of lifestyle may possibly ensure the occurrence of such mystic experiences.
