The color of the sky is not, in reality, a color at all. It is a combination of rays that come from the stars. As mentioned earlier, the distance of these stars is nowhere less than five light years. A ray travels at one hundred eighty-six thousand two hundred eighty-two miles per second, and in this way the measure of a light year can be calculated.
Every star’s light travels, and during this journey the rays collide with one another. To give a name to a single ray is beyond human capacity, and man cannot absorb the color of any one ray through his eyes. The colors that these rays create together are dark, and the eye perceives this darkness as the color of the sky. The atmosphere of this celestial light enters the human head, and as a result, the countless cells within the head become filled with it. They become so saturated that no other quality can enter them except certain specific states.
Each cell has its own condition, or a few cells share similarities, causing their states to mingle. This mixing is not a complete fusion, but rather an overlapping of effects. In this way, the countless cells of the brain interconnect to such an extent that it becomes impossible to distinguish the action or reaction of one from another. Together, they form what we call imagination or perception. It would not be wrong to say that the human being is a creature of imagination. The atmosphere created by these cells can be called imagination, thought, or sensation. This imaginative atmosphere spreads through the brain’s delicate fibers.
The circulation of blood within these fibers becomes rapid, and this very movement is what we call human life. The true nature of blood, as it is generally understood, is actually quite different.
The impressions that the celestial atmosphere leaves upon the brain take the shape of a continuous flow, and in truth, they can only be called imaginations or thoughts. When the atmosphere of the sky color merges into the blood, it activates certain rings within it that have come from other stars. These rings are so minute that even a microscope cannot see them, yet their effects take the form of actions. The same movements are created in the human nerves, and any increase or decrease in them leads to disturbances within the nervous system.
