17:4.2

The Reflective Spirits themselves are true personalities but of such an order as to be incomprehensible to material beings. Even on a superuniverse headquarters sphere they require the assistance of their Image Aids in all personal intercourse with the Ancients of Days and their associates. In contacts between the Image Aids and the Ancients of Days, sometimes one Aid functions acceptably, while on other occasions two, three, four, or even all seven are required for the full and proper presentation of the communication intrusted to their transmission. Likewise, the messages of the Image Aids are variously received by one, two, or all three Ancients of Days, as the content of the communication may require.
