When we look at humanity we find that we can not only divide it into different races and different nations, but we can also divide it into people of different occupations. In this age of materialism, if there is anything that unites us, it is only our material interest. And how long can we be united by a material interest? A friendship formed in materialism is not a friendship which will endure, for in that friendship the one depends upon the other for his own interest. It is sacrifice which enables us to be friends and to Join with one another, and it is in sacrifice that the sign of spirituality is seen. We do not unite together in sacrifice today, our unity is in what we can gain by it. It is a matter for distress that in order to unite we are holding on to a lower ideal which will never prove a center of unity. It is the high ideal which can unite, and that is the hope in which we can unite-if ever we can unite.
