You can only live in the world in one of two conditions: either being a peacemaker or a fighter, but one must be a good fighter in order to win every battle. Life is a continual battle, but warfare does not only ask strength, it requires some sense also. And to be a peacemaker one must be friends with everyone. However insignificant the person is, you must harmonize, else it would be impossible to live. This strain to harmonize causes a strain upon one every day. But still, in trying to harmonize his life becomes easier and easier. And then it's like a wonder-working.
