If one millionth part of the men and women who live in this world simply sit down and for a few minutes say, "You are all God, O ye men and O ye animals and living beings, you are all the manifestations of the one living Deity!" the whole world wil...l be changed in half an hour. Instead of throwing tremendous bomb-shells of hatred into every corner, instead of projecting currents of jealousy and of evil thought, in every country people will think that it is all He. He is all that you see and feel. How can you see evil until there is evil in you? How can you see the thief, unless he is there, sitting in the heart of your heart? How can you see the murderer until you are yourself the murderer? Be good, and evil will vanish for you. The whole universe will thus be changed. This is the greatest gain to society. This is the great gain to the human organism.
