1023. The quiescent, sustaining, form-imparting system is the rigid earth-system, and appears as the osseous system.
2. Process of Heat.
1024. As the heat is the motion of the æther, so is there a system of motion in the organism.
1025. The system, which has no other function to perform than to move, is the muscular system.
1026. The osseous system is related to the muscular system as mass to motion, as Passive to Active. The former maintains the form, the latter changes the same exactly like gravitation and heat.
3. Process of Light.
1027. The light-system must be related to all other spiritual systems and the three fundamental systems of the organism, or to the simply organic systems as light is to matter, being thus polarizing or dominant.
1028. Now the domination of light consists in the sustenance of polarity in all matter. The air itself is preserved in its duplicity only by light. All the points of the organism are polarized by the light-system. The light-system acts consequently through the whole body.
1029. The light-system is not capable of producing matter, like the terrestrial systems. This is self-evident.
1030. It does not polarize by effecting chemical changes. If nevertheless these are present, they are thus only results, occurring while the terrestrial processes are set in action by the process of light.
