sive exertion; always are they the echoes of a backward glance, a reminiscence of the past. Even on Urantia and as you now are, you always find it rejuvenating when for a short time you can suspend the exertions of the newer and higher intellectual efforts and revert to the more simple engagements of your ancestors.
The principles of Urantian play life are philosophically sound and continue to apply on up through your ascending life, through the circuits of Havona to the eternal shores of Paradise. As ascendant beings you are in possession of personal memories of all former and lower existences, and without such identity memories of the past there would be no basis for the humor of the present, either mortal laughter or morontia mirth. It is this recalling of past experiences that provides the basis for present diversion and amusement. And so you will enjoy the celestial equivalents of your earthly humor all the way up through your long morontia, and then increasingly spiritual, careers. And that part of God (the Adjuster) which becomes an eternal part of the personality of an ascendant mortal contributes the overtones of divinity to the joyous expressions, even spiritual laughter, of the ascending creatures of time and space.
The Mansion World Teachers are a corps of deserted but glorified cherubim and sanobim. When a pilgrim of time advances from a trial world of space to the mansion and associated worlds of morontia training, he is accompanied by his personal or group seraphim, the guardian of destiny. In the worlds of mortal existence the seraphim is ably assisted by cherubim and sanobim; but when her mortal ward is delivered from the bonds of the flesh and starts out on the ascendant career, when the postmaterial or morontia life begins, the attending seraphim has no further need of the ministrations of her former lieutenants, the cherubim and sanobim.
These deserted assistants of the ministering seraphim are often summoned to universe headquarters, where they pass into the intimate embrace of the Universe Mother Spirit and then go forth to the system training spheres as Mansion World Teachers. These teachers often visit the material worlds and function from the lowest mansion worlds on up to the highest of the educational spheres connected with the universe headquarters. Upon their own motion they may return to their former associative work with the ministering seraphim.
There are billions upon billions of these teachers in Satania, and their numbers constantly increase because, in the majority of instances, when a seraphim proceeds inward with an Adjuster-fused mortal, both a cherubim and a sanobim are left behind.
Mansion World Teachers, like most of the other instructors, are commissioned by the Melchizedeks. They are generally supervised by the Morontia Companions, but as individuals and as teachers they are supervised by the acting heads of the schools or spheres wherein they may be functioning as instructors.
These advanced cherubim usually work in pairs as they did when attached to the seraphim. They are by nature very near the morontia type of existence, and they are inherently sympathetic teachers of the ascending mortals and most efficiently conduct the program of the mansion world and morontia educational system.
