mortals, these satellites are devoted to the following special phases of study:

1. Sphere number one is occupied with the review of the initial planetary life of the ascending mortals. This work is carried on in classes composed of those who hail from a given world of mortal origin. Those from Urantia pursue such an experiential review together.

2. The special work of sphere number two consists in a similar review of the experiences passed through on the mansion worlds encircling the premier satellite of the local system headquarters.

3. The reviews of this sphere pertain to the sojourn on the capital of the local system and embrace the activities of the remainder of the architectural worlds of the system headquarters cluster.

4. The fourth sphere is occupied with a review of the experiences of the seventy tributary worlds of the constellation and of their associated spheres.

5. On the fifth sphere there is conducted the review of the ascendant sojourn on the constellation headquarters world.

6. The time on sphere number six is devoted to an attempt to correlate these five epochs and thus achieve co-ordination of experience preparatory to entering the Melchizedek primary schools of universe training.

The schools of universe administration and spiritual wisdom are located on the Melchizedek home world, where also are to be found those schools devoted to a single line of research, such as energy, matter, organization, communication, records, ethics, and comparative creature existence.

In the Melchizedek College of Spiritual Endowment all orders—even the Paradise orders—of the Sons of God co-operate with the Melchizedek and the seraphic teachers in training the hosts who go forth as evangels of destiny, proclaiming spiritual liberty and divine sonship even to the remote worlds of the universe. This particular school of the Melchizedek University is an exclusive universe institution; student visitors are not received from other realms.

The highest course of training in universe administration is given by the Melchizedeks on their home world. This College of High Ethics is presided over by the original Father Melchizedek. It is to these schools that the various universes send exchange students. While the young universe of Nebadon stands low in the scale of universes as regards spiritual achievement and high ethical development, nevertheless, our administrative troubles have so turned the whole universe into a vast clinic for other near-by creations that the Melchizedek colleges are thronged with student visitors and observers from other realms. Besides the immense group of local registrants there are always upward of one hundred thousand foreign students in attendance upon the Melchizedek schools, for the order of Melchizedeks in Nebadon is renowned throughout all Splandon.

A highly specialized branch of Melchizedek activities has to do with the supervision of the progressive morontia career of the ascending mortals. Much of this training is conducted by the patient and wise seraphic ministers, assisted by mortals who have ascended to relatively higher levels of universe attainment,
