We see, we must first find the universe which includes all universes; we must find something which, by itself, must be the material running through all these various planes of existence, whether we apprehend it through the senses or not. If we could possibly find something which we could know as the common property of the lower as well as of the higher worlds, then our problem would be solved. Even if by the sheer force of logic alone we could understand that there must be one basis of all existence, then our problem might approach to some sort of solution; but this solution certainly cannot be obtained only through the world we see and know, because it is only a partial view of the whole.
