You see then the immense importance of thinking about the great essentials set forth in the preceding chapters. You must not accept them in any superficial way; you must think about them until they are a part of your central idea. Go back to the matter of the point of view and consider, in all its bearings, the tremendous thought that you live in a perfect world among perfect people, and that nothing can possibly be wrong with you but your own personal attitude. Think about all this until you fully realize all that it means to you. Consider that this is God’s world and that it is the best of all possible worlds; that he has brought it thus far toward completion by the processes of organic, social, and industrial evolution, and that it is going on to greater completeness and harmony. Consider that there is one great, perfect, intelligent Principle of Life and Power, causing all the changing phenomena of the cosmos. Think about all this until you see that it is true, and until you comprehend how you should live and act as a citizen of such a perfect whole.
