Be zealous, and repent

Rudolf Steiner:  "Many who enter esoteric training are very disappointed and say that they had imagined the exercises to be much more energetic and the effects of the exercises to be far more drastic. Those who tell this to themselves should quickly consider the possibility that they are caught in a great error, and that they should make the greatest efforts to correct this error as soon as possible. It is not the exercises that lack enough energy, but rather the individual. It is not the exercises that are ineffective, but rather the person who is not making them effective. By living an esoteric life, the student should become an entirely different person. One must add something new to the old."
