38:4.1

The ninth group of seven primary spheres in the Salvington circuit are the worlds of the seraphim. Each of these worlds has six tributary satellites, whereon are the special schools devoted to all phases of seraphic training. While the seraphim have access to all forty-nine worlds comprising this group of Salvington spheres, they exclusively occupy only the first cluster of seven. The remaining six clusters are occupied by the six orders of angelic associates unrevealed on Urantia; each such group maintains headquarters on one of these six primary worlds and carries on specialized activities on the six tributary satellites. Each angelic order has free access to all the worlds of these seven diverse groups.
