XIII. On the Essential Nature of Illness and Healing

The point now is to bring about a proper harmony between the etheric and the astral activity. The etheric body must be strengthened, the astral weakened. This can be done by bringing the physical substances, which the etheric body has to assimilate, into a condition wherein they lend themselves more readily to its influences than they do in the disease. Likewise the ego-organization must be supplied with added strength; for the astral body, with the animal orientation of its activity, is held more in check when the ego-organization is made stronger in its human organizing power.
