The active forces of the starry world push us into physical incarnation. Clairvoyant perception allows us to see in a person’s organization that he or she is indeed the result of the working together of such cosmic forces. I want to illustrate this in a hypothetical form that nevertheless corresponds fully to clairvoyant perceptions.
If we examined the structure of a person’s brain clairvoyantly and could see that certain functions are located in certain places and give rise to certain processes, we would find that each person’s brain is different. No two people have the same brain. If we could take a picture of the entire brain with all of its details visible, we would get a different picture for each person. If we photographed a person’s brain at the moment of birth and took a picture of the sky directly above his or her birthplace, the two pictures would be alike. The stars in the photograph of the sky would be arranged in the same way as certain parts of the brain in the other picture. Thus, our brain is really a picture of the heavens, and we each have a different picture depending on where and when we were born. This indicates that we are born out of the entire universe.
