"An understanding of the workings of this Principle will give one the key to the Mastery of these rhythmic swings of feeling, and will enable him to know himself better and to avoid being carried away by these inflows and outflows. The Will is superior to the conscious manifestation of this Principle, although the Principle itself can never be destroyed. We may escape its effects, but the Principle operates, nevertheless. The pendulum ever swings, although we may escape being carried along with it."
