A certain direction of life develops for a certain period, and before it has fallen back another direction of life begins to evolve. An individual's view is deluded because evolution seems to him to be a straight evolution, and every fall seems to be a continual fall. After a person has developed in his body and that is finished, perhaps thought might begin its development. If he views the reduction of his body he will feel involution, and if he notices the development of his thought he will realize his evolution. In fact in both ideas he is right; it only depends upon his point of view.
