"That is a very beautiful expression in your last letter, in which you say that you regard life as a casket, in which we can lay up all the spiritual treasures that we possess. It is indeed a remarkably happy idea. In fact, man can make of life what he will, and give as much value to it for himself and others as he has power given him. This, however, is to be understood merely in a spiritual sense, as man has not external circumstances in his own power, but over his spiritual and moral nature he has entire control."
