Life is an illuminated substance. It is a substance that gives off light. And the more highly developed a life is, the greater is the amount of light that the life gives off, and the more brilliant is this light until—in cases of highly developed spirit-lives of the spiritual universe—this light reaches a brilliancy that is unendurable to physical vision and, therefore, blinding to those of us who are of this earth plane.
A spirit-life in all the early stages of its development is a mere speck of light, round or somewhat oval in shape and no larger than a pinpoint—usually not so large. And this is true even of at least some of the life that has attained to a considerable distance on its road to completion.
