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.
When Consciousness descends into the material world, it becomes faint and uncertain due to inertia. All the beings from above that take birth in this world have the same experience.
