AE 587 - "They know not nor understand"

AE 587[7]

. . . that there is no life of intelligence
or of the perception of truth and good
is signified by

"They know not nor understand,
their eyes do not see,
and their hearts do not understand."
(Isaiah 44:18)

It would be too lengthy to explain
what each single thing signifies in particular in this description;
it is only necessary that everyone shall be able to see
that there is something signified more interior and wise
than the mere formation of a graven image.
Let it be known that in this description
heavenly wisdom which is ineffable lies hidden,
and that the angels are in this wisdom
when these things are read by a person,
although the person thinks of nothing
but a graven image and its formation;
for there are here as many correspondences
and as many arcana of wisdom therefrom
as there are words.
