I agree that asceticism can be overdone. It has its place as one means—not the only one—of self-mastery; but asceticism that cuts away life is an exaggeration, though one that had many remarkable results which perhaps could hardly have come otherwise. The play of forces in this world is enigmatic, escaping from any rigid rule of the reason, and even an exaggeration like that is often employed to bring about something needed for the full development of human achievement and knowledge and experience. But it was an exaggeration all the same and not, as it claimed to be, the indispensable path to the true goal.
