Stages of downward penetration of divine nature into a human individuality

Zarathustra had acquired the highest faculties possible to acquire through a physical and etheric body. He had to use the physical instruments prepared in the Solomon line of inheritance, for in them were great and very highly developed forces. He took of this physical nature as much as he could make his own, and blended it with the nature that sprang from the inner force of the Luke Jesus, which had its origin before man's entrance into earthly incarnation. These two natures were now joined in one. Henceforward we have only one being before us.
