“ What we call our astral plane may also be considered as the astral body of the earth. It certainly exists all around us, and interpenetrates the solid earth beneath our feet, but it also extends far away above our heads, so that we may think of it as a huge ball of astral matter with the physical earth in the middle of it, much as the physical body of a man exists within the ovoid form which is filled with astral matter, except that in case of the earth the proportionate size of its astral body outside the physical is enormously greater than in the case of man. ”
