48:2.17

When mansion world ascenders pass from one sphere to another, they are delivered by the transport seraphim to the receivers of the system co-ordinators on the advanced world. Here in those unique temples at the center of the seventy radiating wings wherein are the chambers of transition similar to the resurrection halls on the initial world of reception for earth-origin mortals, the necessary changes in creature form are skillfully effected by the system co-ordinators. These early morontia-form changes require about seven days of standard time for their accomplishment.
