This new religious cast of mind was forging a new iron-curtain, a far more effective one than a physical one. The new mind that was taking over was incapable of understanding deeper things of the spirit; it understood dogmas and creeds; it dropped the law of karma, the theory of the Self. Antoninus, a neo-Platonist of the 4th century predicted that "a fabulous and formless darkness is about to tyrannize over all that is beautiful on earth" (Encyclopaedia of Religion and Ethics, 9.317).
