I shall give you an example of a family I went to see, a Muslim family who lived the typical Muslim life. The middle brother was very fond of music and entertainments. But when his elder brother came to visit he would not have entertainment in the house, and when the younger brother came he would not have entertainment. The reason was that he was too respectful to have entertainment, gaiety before his elder brother. And he was too conscientious to give the example of his gaiety to his younger brother. It is in that way that brothers have regard for each other. When there is such a regard between brothers, then what regard must there not be between the mother, father, children, sister, and relations in the home? If one thinks about it, one can begin to feel that it is a civilization that can always be appreciated, once it is studied and known. And the central theme of it is what? Unity.
