Be not elated at any excellence not your own. If a horse should be elated, and say, ” I am handsome,” it might be endurable. But when you are elated, and say, ” I have a handsome horse,” know that you are elated only on the merit of the horse. What then is your own? The use of the phenomena of existence. So that when you are in harmony with nature in this respect, you will be elated with some reason; for you will be elated at some good of your own.
