Man's Threefold Nature and Relationship to Remedies

But let us consider a—shall we say—somewhat more highly placed activity of ours; the metamorphic activity of the etheric element, the metamorphosis of light, as just described. In respect of these functions we are on the same grade as birds. We have a large intestine and a bladder in our physical organism, but in our etheric organism, in these respects, we are birds; these organs are actually absent in the dynamics of the cosmos. Therefore we are obliged to work up light as soon as we receive it, and to give forth the products by excretion. If a disturbance arises here, there is no corresponding organ for its operation. We cannot stand the disturbance without our health suffering accordingly. So when we observe the birds with their miniature brains, it becomes evident that in the macrocosmos they are replicas of our more subtle organisation. And if you want to study man with reference to this finer organisation which separates itself from his coarser organisation which has descended below the birds—then, my friends, you must study the processes of the world of birds macroscopically.
