66:4.10

In conformity to their instructions the staff did not engage in sexual reproduction, but they did painstakingly study their personal constitutions, and they carefully explored every imaginable phase of intellectual (mind) and morontia (soul) liaison. And it was during the thirty-third year of their sojourn in Dalamatia, long before the wall was completed, that number two and number seven of the Danite group accidentally discovered a phenomenon attendant upon the liaison of their morontia selves (supposedly nonsexual and nonmaterial); and the result of this adventure proved to be the first of the primary midway creatures. This new being was wholly visible to the planetary staff and to their celestial associates but was not visible to the men and women of the various human tribes. Upon authority of the Planetary Prince the entire corporeal staff undertook the production of similar beings, and all were successful, following the instructions of the pioneer Danite pair. Thus did the Prince’s staff eventually bring into being the original corps of 50,000 primary midwayers.
