What is the fourth sphere?

Happy faces await the stranger who may come with the sign of admittance or guides to usher them into the wondrous abode where all scenes are adapted to the higher works of art, knowledge and scientific schools, which makes the fourth sphere one of the most interesting spheres for investigation.

And oh! the immensity and variety of scenery, gorgeous homes, grand mansions, palaces, towers, minarets, temples, colleges and schools.

The arts and sciences are here very much advanced—ready to be carried to other spheres. 

This is the laboratory and workshop for all spheres. 

There is also much of the beautiful and grand of other spheres. The older artists and sages of earth's early history have here left their handiwork before passing on to the higher, and more glorious knowledge. 

All is bustle in this world of living, acting, animated intelligence, giving forth new life, new thoughts to our world. 

This is the true working sphere where the inhabitants of many are drawn to investigate the true secret of material and spiritual essences. 

The scenery of this sphere is of an Italian character of mountains and glorious sunsets. 

Its waters sparkle and ripple like life, emitting a transporting, revivifying influence to the atmosphere—and all is life.

—Martha Washington in Spirit
