True exaltation of the spirit resides in the fact that it has come to earth and has realized there its spiritual existence. It is this which is the perfection of spirit. Therefore all that the world gives in the way of knowledge, of experience, or of reason, all that a man's own experience or that of others teaches, all that is learnt from life, its sorrows and disappointments, its joys and opportunities, all these contradictory experiences help our love to become fuller and our vision wider. A man who has gone through all experiences and has held his spirit high and has not allowed it to be stained, such a man may be said to be pure-minded. The person who could be called pure because he had no knowledge of either good or evil would in reality be merely a simpleton. To go through all which takes away the original purity and yet to rise above everything which seeks to overwhelm it and drag it down, that is spirituality; the light of the spirit held high and burning clear and pure. It needs the effort of a whole lifetime, and he who has not known it has not known life.
