, filling it with the knowledges of truth and good, and adapting to
them the knowledges (scientiae) that are from world, for the sake of
proof and agreement. Thus man has a rational, and thus he has an
understanding. He who believes that man has a rational and an
understanding before his natural has been purified from evils is
deceived, for the understanding is seeing truths of the church from the
light of heaven; and the light of heaven does not flow into those not
purified. And as the understanding is perfected, the falsities of
religion and of ignorance and all fallacies are dispersed. (A.E., n.
941.)

When a man has been admitted by the opening of his internal into heaven,
and receives light therefrom, the same affections that angels of heaven
have, with their pleasures and delights, are communicated to him. The
first affection then granted is an affection for truth; the second is an
affection for good; and the third is an affection for bringing forth
fruits. For when a man has been admitted into heaven and into its light
and heat he is like a tree growing from its seed. His first budding
forth is from enlightenment; his blossoming before the fruit is from an
affection for truth; the putting forth of fruit that follows is from an
affection for good; the multiplication of itself again into trees is
from an affection for producing fruit. The heat of heaven, which is
love, and the light of heaven, which is the understanding of truth from
that love, bring forth in subjects of life things like those that the
heat of the world and its light bring forth in subjects not of life.
That like things are brought forth is from correspondence. But in both
cases the production is effected in springtime; and springtime in man is
when he enters heaven, which is effected when his spiritual internal is
opened; before that it is the time of winter to him. (A.E., n. 942.)

Man has affection for truth when he loves truth and turns away from
falsity. He has an affection for good when he loves good uses and turns
away from evil uses. He has an affection for bringing forth fruit when
he loves to do goods and to be serviceable. All heavenly joy is in
these affections and from them, and this joy cannot be described by
comparisons, for it is supereminent and eternal. (A.E., n. 943.)

Into this state the man comes who shuns evils because they are sins, and
looks to the Lord; and so far as he comes into this state he turns away
from an
