No doubt one cannot always say that it is an element which attracts the same element; but also the element attracts what it is lacking, what is opposite to it. And when we think of friendship, we see that with some we feel inclined to be friends and others we feel inclined to keep away from. And the most interesting part is that those whom we feel disinclined to be friends with, they have also some who are drawn towards them in friendship. This takes us to find the truth which lies in musical harmony, how two notes have a relation with one another and their combination brings about a harmony.
