Nature is conquered by man every day. As a race, man is manifesting his power. Try in imagination to put a limit to this power in man. You admit that man as a race has infinite power, has [an] infinite body. The only question is what you are. Are you the race or one [individual]? The moment you isolate yourself, everything hurts you. The moment you expand and feel for others, you gain help. The selfish man is the most miserable in the world. The happiest is the man who is not at all selfish. He has become the whole creation, the whole race and God [is] within him. . . . So in dualism — Christian, Hindu, and all religions — the code of ethics . . . . is: Do not be selfish . . . . things for others! Expand! . . . .
