1. The Mystery of Golgotha I
We know that, starting from ‘I,’ the physical body also can be transformed. This transformation takes place consciously through what is taught in esoteric training. All that the pupil can learn with the intellect, all that influences his astral body is only the preparation; the training begins when the ‘I’ begins to work upon the etheric body, when he conquers his temperament, his inclinations and habits, when he becomes a different man. Through this he gains insight into the higher worlds. All that he learns, all that gives him a theoretical insight, all sciences, only influence the astral body; but all that works upon his etheric body gives such an impetus to his development that gradually the spiritual organs are formed in him and he begins to see in the higher worlds. Thus we see how the astral body and etheric body are transformed. That which transforms the physical body comes from the breathing process; this purifies and spiritualises the physical body. Christian esotericism calls this the Father. We have to distinguish that as much as a person has within him of what purifies and transforms the astral body, so much has he of the Holy Spirit within him.
