^48:4.15 When we are tempted to magnify our self-importance, if we stop to contemplate the infinity of the greatness and grandeur of our Makers, our own self-glorification becomes sublimely ridiculous, even verging on the humorous. One of the functions of humour is to help all of us take ourselves less seriously. Humour is the divine antidote for exaltation of ego.

^48:4.16 ¶ The need for the relaxation and diversion of humour is greatest in those orders of ascendant beings who are subjected to sustained stress in their upward struggles. The two extremes of life have little need for humorous diversions. Primitive men have no capacity therefor, and beings of Paradise perfection have no need thereof. The hosts of Havona are naturally a joyous and exhilarating assemblage of supremely happy personalities. On Paradise the quality of worship obviates the necessity for reversion activities. But among those who start their careers far below the goal of Paradise perfection, there is a large place for the ministry of the reversion directors.

^48:4.17 The higher the mortal species, the greater the stress and the greater the capacity for humour as well as the necessity for it. In the spirit world the opposite is true: The higher we ascend, the less the need for the diversions of reversion experiences. But proceeding down the scale of spirit life from Paradise to the seraphic hosts, there is an increasing need for the mission of mirth and the ministry of merriment. Those beings who most need the refreshment of periodic reversion to the intellectual status of previous experiences are the higher types of the human species, the morontians, angels, and the Material Sons, together with all similar types of personality.

^48:4.18 Humour should function as an automatic safety valve to prevent the building up of excessive pressures due to the monotony of sustained and serious self-contemplation in association with the intense struggle for developmental progress and noble achievement. Humour also functions to lessen the shock of the unexpected impact of fact or of truth, rigid unyielding fact and flexible ever-living truth. The mortal personality, never sure as to which will next be encountered, through humour swiftly grasps — sees the point and achieves insight — the unexpected nature of the situation be it fact or be it truth.

^48:4.19 ¶ While the humour of Urantia is exceedingly crude and most inartistic, it does serve a valuable purpose both as a health insurance and as a liberator of emotional pressure, thus preventing injurious nervous tension and overserious self-contemplation. Humour and play — relaxation — are never reactions of progressive 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.

^48:4.20 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 humour 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 humour 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.

5. THE MANSION WORLD TEACHERS

^48:5.1 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.

^48:5.2 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.

^48:5.3 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.

^48:5.4 ¶ 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.

^48:5.5 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.

^48:5.6 In the schools of the morontia life these teachers engage in individual, group, class, and mass teaching. On the mansion worlds such schools are organized in 3 general groups of 100 divisions each: the schools of thinking, the schools of feeling, and the schools of doing. When you reach the constellation, there are added the schools of ethics, the schools of administration, and the schools of social adjustment. On the universe headquarters worlds you will enter the schools of philosophy, divinity, and pure spirituality.

^48:5.7 ¶ Those things which you might have learned on earth, but which you failed to learn, must be acquired under the tutelage of these faithful and patient teachers. There are no royal roads, short cuts, or easy paths to Paradise. Irrespective of the individual variations of the route, you master the lessons of one sphere before you proceed to another; at least this is true after you once leave the world of your nativity.

^48:5.8 One of the purposes of the morontia career is to effect the permanent eradication from the mortal survivors of such animal vestigial traits as procrastination, equivocation, insincerity, problem avoidance, unfairness, and ease seeking. The mansonia life early teaches the young morontia pupils that postponement is in no sense avoidance. After the life in the flesh, time is no longer available as a technique of dodging situations or of circumventing disagreeable obligations.

^48:5.9 ¶ Beginning service on the lowest of the tarrying spheres, the Mansion World Teachers advance, with experience, through the educational spheres of the system and the constellation to the training worlds of Salvington. They are subjected to no special discipline either before or after their embrace by the Universe Mother Spirit. They have already been trained for their work while serving as seraphic associates on the worlds native to their pupils of mansion world sojourn. They have had actual experience with these advancing mortals on the inhabited worlds. They are practical and sympathetic teachers, wise and understanding instructors, able and efficient guides. They are entirely familiar with the ascendant plans and thoroughly experienced in the initial phases of the progression career.
