Now coming to brotherhood. How is it, that the brotherhood which existed in the world could have allowed a catastrophe to take place like the one we have gone through. And the answer to the question is: it was a brotherhood among nations and not of nations. Nations became brothers of nations for some self-interest. The nature of love is to progress, to expand. When brotherhood did not go further than nations it had to have an undesirable result. For a long time during the period of modern civilization the tendency has been like that of somebody who is only concerned about the welfare of his family. Selfishness on the part of an individual very often seems profitable in life, but it never ends in harmony and peace.
