The Graduate Guides, as a group, sponsor and conduct the high university of technical instruction and spiritual training which is so essential for our goal. They are engaged in piloting the pilgrims of time through the seven circuits of Havona worlds.; stay with same pilgrim throughout. 
The number of Graduate Guides is beyond the power of human minds to grasp. They have not existed from eternity; they mysteriously appear as they are needed.Malvorian was the first, the Guide of the graduated called Grandfanda, and now is the chief of their supreme council.  Graduate Guides never leave the Havona worlds; they are dedicated to the service of the graduate pilgrims of time and space. 
Though evolution is not the order of the central universe, it is believed that the Graduate Guides are the perfected or more experienced members of another order of central universe creatures, the Havona Servitals. 
For example, Sudna is a servital returned from superuniverse service, was received on Paradise, met the Father, entered the divine embrace and is no more, and three days later a newborn Graduate Guide appeared “spontaneously” in Havona. 
The newly created servitals, together with newly appearing Graduate Guides, all pass through the courses of training which the senior guides continuously conduct on each of the seven Havona circuits. They then go to great lengths to serve on the study worlds surrounding the headquarters spheres of the seven superuniverses.  In personality records they appear as single-origin beings in the family of the Infinite Spirit.  Graduate Guides, with their servital associates, minister on all circuits of Havona to both ascending and descending pilgrims.
