11:3.1

On upper Paradise there are three grand spheres of activity, the Deity presence, the Most Holy Sphere, and the Holy Area. The vast region immediately surrounding the presence of the Deities is set aside as the Most Holy Sphere and is reserved for the functions of worship, trinitization, and high spiritual attainment. There are no material structures nor purely intellectual creations in this zone; they could not exist there. It is useless for me to undertake to portray to the human mind the divine nature and the beauteous grandeur of the Most Holy Sphere of Paradise. This realm is wholly spiritual, and you are almost wholly material. A purely spiritual reality is, to a purely material being, apparently nonexistent.
