4. The Unification of Humanity through the Christ Impulse
We must therefore distinguish between the uniform earthly forces working all over the earth that would make all human forms the same and the forces working out of the universe on the earth, making each etheric body different. We can see the differences between etheric bodies through spiritual scientific research. At the one extreme are those etheric bodies that have strong forces and are tough, retaining their form almost as much as we do our physical form. This is one kind of etheric body. There is a second kind that is mobile, like something that is fluttering and always in movement, flowing and moving. But these two kinds of etheric bodies still reveal themselves in such a way that we can describe their inner tone and shading as being more or less alike. There is another kind of etheric body that is inwardly tinted, inwardly shimmering, not uniform in color but having various tones and colors. There is a fourth kind of etheric body that has one primary color throughout its whole substance, but this color changes over time though we cannot pinpoint other than purely inward causes for this. These etheric bodies are not shimmering in different colors or shaded in many tones; they have only one color, but they change it in the course of time. We may call them chameleon-like etheric bodies.
