48:2.1

These unique beings are exclusively concerned with the supervision of those activities which represent a working combination of spiritual and physical or semimaterial energies. They are exclusively devoted to the ministry of morontia progression. Not that they so much minister to mortals during the transition experience, but they rather make possible the transition environment for the progressing morontia creatures. They are the channels of morontia power which sustain and energize the morontia phases of the transition worlds.
