The idea, so common in the ancient writers, is not all a poetic conceit, that the soul of a man is only a fragment of a larger whole, and goes out in search of other souls in which it will find its true completion. We walk among worlds unrealized, until we have learned the secret of love. We know this, and in our sincerest moments admit this, even though we are seeking to fill up our lives with other ambitions and other hopes. In spite of the vulgar materialism of our day, we do feel that the spiritual side of life is the most important, and brings the only true joy. And friendship in its essence is spiritual. It is the free, spontaneous outflow of the heart, and is a gift from the great Giver.
