Those who have come upon earth fully conscious of their entire being and conscious of their Origin, there is at first a period when this consciousness gets veiled by the physical life and the body-consciousness.
All life on earth is governed by vital beings' influence. For earth to be entirely divine and harmonious, these beings must be conquered, transformed, or return to their origin.
Fully conscious beings recall their purpose and continue their work at night while their bodies rest, they remember what they were and what they can do.
