Man's Threefold Nature and Relationship to Remedies

You will gather from this that the organisation of man needs not only ponderable substances, derived from the external world and transformed, but that imponderable, etheric substances are also present within him, although in metamorphosis. Further you will conclude that these basic principles afford the possibility of building up a correct view, on the one hand, of the healing effect of the sun's light: we can expose the human being directly to the sunlight, in order to regulate his disordered interrelation to the environing light. And, on the other hand, we may administer internally those substances that counteract the irregularity in the deprivation of transmuted light. We must counter-balance the deprivation of transmuted light, by means of what can be drawn from the remedial substances. There is the window through which you can observe the human organisation at work.
