You know, it is sometimes an ideal not to have any kind of convictions or feelings that are not based upon reality. One must even educate people...that their emotions ought to have a real basis, that they cannot swear hell and damnation at somebody on a mere assumption, and that there are absolute reasons why they are not justified in doing such a thing. They really have to learn that their feelings should be based on facts.But to [develop further] one should unlearn all that. One should even admit that all one's psychical facts have nothing to do with material facts. For instance, the anger which you feel for somebody or something, no matter how justified it is, is not caused by those external things. It is a phenomenon all by itself. That is what we call taking a thing on its subjective level. ...If you have reached that level...you have succeeded in dissolving the absolute union of material external facts with internal or psychical facts. You begin to consider the game of the world as your game, the people that appear outside as exponents of your psychical condition. Whatever befalls you, whatever experience or adventure you have in the external world, is your own experience.
