The purpose and mission of Scientific GOD Journal (http: //www.scigod.com) are to conduct scientific inquiries on the nature and origins of life, mind, physical laws and mathematics and their possible connections to a scientifically approachable transcendental ground of existence - we call "Scientific GOD." We believe that in this Golden Age of Science the GOD in whom we trust should be spiritual as well as scientific. Indeed, since we are all made out of the same subatomic, atomic and genetic alphabets, the scientific GOD each of us seeks should be one and the same whatever our race, religion and other differences. This is Scientific GOD Journal Volume 4 Issue 4 first published in May, 2013. It is entitled "Concealment-Revelation of God by Experience & Towards a Meaningful Unfolding Universe" and contains the following Articles: (1) The Experiential Basis of Maya: How God Uses Experience to Both Conceal and Reveal Itself (Part I) (2) The Experiential Basis of Maya: How God Uses Experience to Both Conceal and Reveal Itself (Part II); (3) Towards a Meaningful Unfolding Universe (Part I); (4) Towards a Meaningful Unfolding Universe (Part II); and (5) On Bernard Haisch's God Theory.
