This Manifesto is based on the specifically human relevance of the Theory of Absolute Relativity, which establishes God on the grounds of Science, not religion of any kind. "Mir" is a Russian word meaning both "world" and "peace", so, Mirism is a new ideology aimed at world peace and fraternity by means of nonviolent and benevolent education toward general character integrity and moral maturity. Mirism consists of a general framework filled by a strict ethical code. The general frame-work includes such propositions as the rebuilding of the Temple in Jerusalem, transforming Israel into a constitutional monarchy, and a fundamental change of Jewish identity, for examples. Attitude change and moral maturity should pave the way for Man to peacefully colonize outer space and evolve into the Cosmic Era by gradually becoming Cosmic Man. Such desirable future may be likened to the "Kingdom of God", which, although presently utopia, is attainable with the help of Mirism for the benefit of all Mankind.
