AE 517 - two states of thought

AE 517 [3]
There are two states of a person's thoughts,
one when from the Lord he is in thought respecting truths,
the other when from himself.
When from the Lord he is in thought respecting truths
his mind is elevated even into the light of heaven,
from which he has illustration and right perception of truth;
but when from himself he is in thought respecting truths,
his mind falls into the light of the world;
and that light, in respect to things spiritual,
or the things of heaven and the church,
is thick darkness,
in which a person sees only such things
as shine from the fire or the love of self and of the world,
and these in themselves are falsities that are opposites of truths.
