There are three stages of action which the sincere followers of the message have to pass through, and the difficulty is that each stage has a tendency to hinder them from going on to the next stage. And the reason is that there is no end of interest and happiness at every stage that they have to go through in their lives. Another reason is that one stage is quite different from another, and therefore each stage has a kind of contrary action to the previous one. These three stages may be called receiving the message, assimilating the message, and representing the message.
