But there are certain secret brotherhoods who have made it their task to work for the opposite of this.They want to have the wisdom only within their closest circle so that they can use it in the service of their own lust for power. This is the battle we are now fighting.On the one hand there is the need to guide humanity in the right way by letting people take in the spiritual wisdom. On the other there are the closed brotherhoods of a nasty kind whose very aim is NOT to let the wisdom enter into humanity, so that people will remain stupid and foolish as far as the spiritual world is concerned while those within the closely guarded brotherhoods carry on their machinations there.
