What is the 5th level of heaven?

In the fifth sphere you find the alabaster and crystal homes, which are substance ethereal to the touch of spirits who do not belong to this sphere, yet well defined to those who inhabit it. 

The architecture is far beyond that of mortal conception. 

Many of these habitations have been seen by the clairvoyant eye and spoken of in Bible times. It has been considered the heaven, but is only one locality and only the fifth degree. Here come the mighty sages and prophets of ancient days, as well as the teachers of the present. It is the home of Washington, Paine, and all the honored of their age. These noble beings also have homes in the upper spheres. Advanced spirits have homes in all spheres wherever they can come in harmony, like different residences on earth when adapted to their needs at certain times. Some have homes like the sunbeams, so bright and ethereal, where the zephyrs float perfumed and charmed music from the upper spheres can reach them. Many times they converse with those of the higher life and often are led to do their bidding.

This sphere is universal ground to the inhabitants above where all who wish can mingle and express any new thought or discovery—where a thorough feeling of interest is taken in the subject advanced.

It is where facts are gathered and propounded—notes taken and kept for further reference until it is solved, and when approved is assigned its place and brought into use as far as can be made practicable. Oftentimes this class of spirits are pushing on to new fields, exploring after the divine cause of all matter and find much to expose of the fabulous tales of the past and much that is retained—still analyzing and removing the dross from the grand germ of truth.
