II. Esoteric Christianity

If we say, when speaking of our present physical body, that it is composed of the same physical and chemical substances and forces to be found in the minerals out in the cosmos, it must, nevertheless, be quite clear to us that there is an enormous difference between this physical human body and the mineral. Speaking in very elementary terms, we emphasize the difference between the physical human body and the physical body of a mineral—for example, of a rock crystal—when we say that the rock crystal retains its form unless shattered from without. The human physical body, on the contrary, cannot of itself retain its form. It has its form only because and as long as there are within it an ether body, an astral body, and an ego. The moment the ether body, the astral body, and the ego are separated from it, it becomes something quite different from what it is between birth and death; it follows the laws of the physical and chemical substances and forces and decays, while on the other hand the physical body of the mineral remains unchanged.
