All heaven's delights are united to uses and inhere in them, because
uses are the goods of love and charity, in which the angels are. The
angels find all their happiness in use, from use, and according to
use. There is the highest freedom in this because it proceeds from
interior affection, and is conjoined with ineffable delight. Uses
exist in the heavens in all variety and diversity. Never is the use of
one angel quite the same as that of another; nor the delight. What is
more, the delights of any one person's use are countless. These
countless and various delights are nevertheless united in an order so
that they mutually regard one another, as do the uses of every member,
organ and inner part of the body. They are even more like the uses of
each vessel and fibre in every member, organ and vital part; each and
all of which are so related that they regard each of its own good in
the other, and thus in all, and all in each. As a result of this
general and several regard they act as one.
