18:2.4

The architecture, natural embellishment, morontia structures, and spirit creations are exclusive and unique on each sphere. Every world is a place of everlasting beauty and is wholly unlike any other world in the central universe. And you will each spend a longer or shorter time on each of these unique and thrilling spheres on your way inward through Havona to Paradise. It is natural, on your world, to speak of Paradise as upward, but it would be more correct to refer to the divine goal of ascension as inward.
