This same method can be extended from psychology to esotericism. In esotericism we have a problem before us. There is a truth which we have to discover, which is obscured by a fact; and if we become accustomed to deny a fact in order to discover a truth, we will be ready then in esoteric work to discover that truth which is worth discovering. The fact is a shadow which for the moment represents something which has a certain meaning attached to it, which we can witness, but which at the same time will not continue to be real for ever. For instance a person says, "Sandow, in fact, is a strong man." Yes it is a fact that he is a strong man, but because he will not be eternally strong it is only a fact, it is not a truth. Therefore the knowledge of the existence of others, all this knowledge that we have is a changeable knowledge, and since it is changeable it is a fact; truth is behind it.
