XIII. On the Essential Nature of Illness and Healing

Now the question arises, does sulphur also play a part in the transition from the domain of etheric action to that of astral, and has it anything to do with the ego-organization? It does not combine appreciably with inorganic substances introduced into the organism so as to form salts or acids. Such a combination would provide the basis for a reception of the sulphur processes into the astral body and ego-organization. We see, therefore, that sulphur does not penetrate into these regions. It unfolds its activity in the realm of the physical and etheric body. This is also shown by the fact that an increased supply of sulphur to the organism gives rise to feelings of giddiness, reduction of consciousness. Sleep, too, i.e. the condition of the body when the astral and ego-organization are not working as soul being, grows more intense when the supply of sulphur is increased.
