Atmospheric Composition, Organ Systems, and Healing Substances

These matters compose a bundle of questions, upon which I will base our next lectures. The most fruitful approach will be from the consideration of another remarkable circumstance, which perhaps only the spiritual scientist can fully appreciate. As you are aware, oxygen and nitrogen are mingled in our atmosphere; they are loosely mingled in a manner which cannot be exactly defined, either in the terms of physics or of chemistry. And we, as men and as earthly beings, are wholly enmeshed in the combined activities of these two elements, oxygen and nitrogen, and one can therefore assume from the outset that there is some significance in the relation of oxygen to nitrogen in our atmosphere, and in their normal ratio.
