AC 3671 - growing seeds

AC 3671 [2]
Understanding good and truth and willing them
is the function of the rational,
and perceptions of good and truth 
resulting from this
are like seeds;
but knowing them and doing them
is the function of the natural.
Facts and deeds are like the soil.
When a person has an affection for the facts
that corroborate what is good and true,
the more so when he experiences joy
in bringing them into act,
those facts are seeds
that are present and growing in the natural
as their own proper soil;
and there they grow.
As a consequence good is made fruitful
and truth is multiplied,
and they are constantly springing up out of that soil
into the rational and perfecting it.
The situation is different
when a person understands what is good and true,
and also interiorly perceives that he wills something,
and yet does not desire to know these things,
let alone do them.
 In that case good cannot be made fruitful
nor truth be multiplied within the rational.
