6. Tree of Knowledge II
It is obvious that in face of such facts of the spiritual world, it can be asked: how does one protect oneself from such things? The answer could only be given by referring the questioner to a gradual working himself out of the illusions of life in which he is only too deeply held. The grounds of self-deception are above all present when a man thinks he does not in the least deceive himself but only looks at facts. Only the good will, therefore, to undertake one's self-development from this standpoint, only this helps one to escape from these things. One thing above all, my dear friends, is necessary: to understand how the impulses of spiritual science work when we strive for self-perfecting, but how much we are inclined to attribute far more selflessness to ourselves than we are really entitled to do. By saying this I wish to give you a golden rule.
