"He envisions that Judaism along with all other historical forms of religion will one day be renewed by a “pure” (or core) religion grounded in the dignity of all persons and a community committed to the internal commonweal of God to encourage moral effort. This God is no highest Being (ens summum) among beings but the Being of all beings (ens entium), as the unconditional condition of possibility for any and all reality and the origin of both the physical order that governs nature and the moral order that governs creative freedom."
All religions unified through one doctrine consisting of the eternal, unbounded, harmonious, immutable, perfect, and sublime primary essence governing the physical structure and moral character of nature and cognition—it's no wonder why the Upanishad-touting Schopenhauer idolized him as the greatest philosopher of his day. Also, Schopenhauer despised Jews for their denial of metempsychosis in the Book of Daniel (if I remember that correctly) and went on to cite the influence of their religious system as a "stink." Sometimes I wonder what really drove Nietzsche to revolt from this inheritance of moral disposition and conceive his immorality.
