"The secret of all future development is a recognition that everything achieved by man from a right comprehension of evolution is a sowing of seed which must ripen into love. And the greater the amount of love-force, so much the greater will be the creative force available for the future. In that which will grow from love, will lie the mighty forces leading to that culminating point of spiritualization described above... Spiritual knowledge is transmuted through its own nature into love... The wisdom of the outer world becomes inner wisdom in man from the Earth period onward and when it is concentrated in him, it becomes the germ of love. Wisdom is the necessary preliminary condition for love; love is the fruit of wisdom, reborn in the ego."
