P268:8, 24:5.1 The Assigned Sentinels are co-ordinating personalities and liaison representatives of the Seven Supreme Executives. They were personalized on Paradise by the Infinite Spirit and were created for the specific purposes of their assignment. They are of stationary numbers, and there are exactly seven billion in existence.
P269:1, 24:5.2 Much as an Associate Inspector represents the Seven Supreme Executives to a whole local universe, so in each of the ten thousand systems of that local creation there is an Assigned Sentinel, who acts as the direct representative of the far-distant and supreme board of supercontrol for the affairs of all seven superuniverses. The sentinels on duty in the local system governments of Orvonton are acting under the direct authority of Supreme Executive Number Seven, the co-ordinator of the seventh superuniverse. But in their administrative organization all sentinels commissioned in a local universe are subordinate to the Associate Inspector stationed at universe headquarters.
P269:2, 24:5.3 Within a local creation the Assigned Sentinels serve in rotation, being transferred from system to system. They are usually changed every millennium of local universe time. They are among the highest ranking personalities stationed on a system capital, but they never participate in deliberations concerned with system affairs. In the local systems they serve as the ex officio heads of the four and twenty administrators hailing from the evolutionary worlds, but otherwise, ascending mortals have little contact with them. The sentinels are almost exclusively concerned in keeping the Associate Inspector of their universe fully informed on all matters relating to the welfare and state of the systems of their assignment.
P269:3, 24:5.4 Assigned Sentinels and Associate Inspectors do not report to the Supreme Executives through a superuniverse headquarters. They are responsible solely to the Supreme Executive of the superuniverse concerned; their activities are distinct from the administration of the Ancients of Days.
P269:4, 24:5.5 The Supreme Executives, Associate Inspectors, and Assigned Sentinels, together with the omniaphim and a host of unrevealed personalities, constitute an efficient, direct, centralized, but far-flung system of advisory and administrative co-ordination of all the grand universe of things and beings.
