What is the third sphere of heaven?

You find a wonderful likeness to some portions of earth in the third sphere, especially the tropics, with their luxuriant shrubs and flowers, birds of beautiful plumage and melodious song. 

Amid these scenes spirits have lofty mountains whose tops are crowned with verdure, while some have the beautiful snow—or whose pure, white, feathery softness resembles the snow of earth, yet not the same in texture. 

Beautiful flowers, of pink and rosy hue, cover the surface, emitting a fragrance that fills the atmosphere with a living presence of their exhalations. 

Sections of this sphere are covered by towns and villages filled with earnest, working beings, who are carrying out their plans of life as upon earth being satisfied to live and move within the limits of its conditions. 

Here are grand old plantations with scenery and domestic life so real, so earnest, that they are tempted to mingle with them in their pursuits, for they feel that it is only a matter of condition, which causes them to be happy and contented with associations that please them. 

Architecture is here primitive like the tropics, hence they find many who live in the open air under the arches of the loveliest trees of which the mind can conceive.

This sphere has been assigned to the primitive or unfolded children of earth where according to their requirements, they can be educated and prepared to pass to to a higher sphere when duties will be assigned according to their tastes and capacities, which sphere is an intellectual and mechanical one. In this they are prepared to enter the higher associations of life among the scientific and literary.

Each sphere is a school of preparation for the one still higher, purifying for the glory awaiting.

Ofttimes, many from the second, third and fourth spheres return to earth to gather knowledge—or leave some dross or deformity that must be removed before they can progress into the inner sanctuary of spiritual light and life.
