A corresponding spiritual concept or corresponding
symbolic meaning is bound up with the object to which
it corresponds. It is like the bond between our eyesight
and our eye, or between our hearing and our ear. It is like
the bond connecting our thoughts (which are spiritual)
with the form of our interiors and through this with the
organs of speech. Or it is like the bond connecting our
will (which is also spiritual) with the muscle fibers we
use when we act. That is the relationship that every corresponding
spiritual attribute or symbolic meaning has
with the earthly counterpart to which it corresponds.
