AC 5173 - an inward active force

AC 5173 [2 & 3]
... the truth is that in all and each of the things of nature
and her three kingdoms
there is an inward active force from the spiritual world;
and unless this were so,
nothing whatever in the natural world could act as cause and effect,
and consequently nothing could be produced.
... for to think and will is spiritual,
and to act and be moved is natural.
