11. From Jesus to Christ
Here I can only indicate what in earlier lectures and in such books as An Outline of Occult Science and Knowledge of the Higher Worlds and Its Attainment, I have already explained, namely, that the soul can completely change itself. Through practicing certain exercises, the soul may bring about an infinite enhancement of its inherent forces of attention and devotion. Ordinarily, the soul-spiritual life uses the human body like an instrument. Just as hydrogen is bound to oxygen in water, so is this life closely connected with the body, within which it works. Now, just as hydrogen may be separated from oxygen and shown to have completely different qualities from water, so may the soul, through the exercises described in Knowledge of the Higher Worlds, separate itself from the body. By thus turning away from and lifting itself out of the body, the soul acquires an inner life of its own.
