To say that results are according to deeds sounds simple, for almost everyone knows it. But not everyone always follows it; and the reason is that knowing a law does not necessarily enable man to observe that law. Besides the nature of life is so intoxicating that, absorbed in the activity of life, one mostly forgets this rule. It is natural, however, that this most simple thing should be very difficult to practice, because one generally neglects to think seriously about it. In order to prove this theory, that the results of a deed are similar to the deed, one need not go far; one can see numberless examples in one's own life and in the lives of others. For it is like an echo; what one does has an echo, and in that echo is the result.
