"People have forgotten, or rather do not want to admit, the great cosmic significance of love. The materialism of our age puts love on the level of a purely physiological function. At best, love today is treated as a psychological process. But if the cosmic significance of love could be realized once more, people would see in love its highest function, i.e., the awakening of all the highest emotions and creative abilities."
