Lebenswert" is 3 books in one, the already published and available "Weltwesen", "Weltheil", and "Judenwelt". The first book examined what's beyond the limits of the Universe, and discussed the nature, structure, function, and relevance of the Absolute. The second book is concerned with the human relevance of the Absolute, and that is cosmic morality, various optimal function 'mechanisms' under the common term optimal efficiency. Morality is discussed as a subset of Absolute Ethics, via cosmodynamics, the modus operandi of the Absolute. The third book is specifically concerned with the Jewish relevance of the Absolute, and it is suggested that Jews may still fulfill their original mission of becoming light unto the nations and serving God by teaching ethical monotheism and righteousness. With such assistance, Man can grow into Cosmic Man, attain moral maturity, and enter the Cosmic Era in peace and harmony with Nature.
