The Mind back of things has not allowed the discovery of the atom bomb to be made just at this particular time without sufficient reason for doing so. Humanity is being prepared for the next fated move in its inner life. And that is a lessening of selfish materialism, an increasing of spiritual co-operation. The instrument used is a physical one though the net result will include a psychological one. Only if the fear generated by the unprecedented danger of this discovery attains such a tremendous magnitude that it overwhelms all other base emotions, is it likely to lead to the unshakeable determination to make the fresh moral start that is needed. The method of persuasion has changed radically. Where the spiritual teachers have failed to bring home their lessons to humanity, the atomic bomb may do so. It has forced these alternatives upon us: either the nations of the world must change their moral attitude towards each other or they must annihilate each other.
