Therefore the Prophets and Masters have warned mankind against the intoxication of self-interest and egoism. The world, the nation, the family can be pictured as one single body and when one part of the body has pain although the other part has no pain, the person feels sick. Therefore you can never be happy unless you see your brother and your neighbor happy also. But very few people think this way; very few see it from the true point of view. All efforts as socialism, league of nations, all peace movements are striving to bring a better understanding, to bring peace and brotherhood but the ideal is not realized. It can be seen in the teachings of the Masters who have come from time to time to earth to give light to humanity. It does not mean that all these efforts directed to harmony and brotherhood are wasted, but the essential part is missing.
