exclude higher thought if they are controlled, so in the astral world as in
the physical a man may devote himself to study and to helping his fellows,
or he may waste his time and drift about aimlessly.

The astral world extends nearly to the mean distance of the orbit of the
moon; but though the whole of this realm is open to any of its inhabitants
who have not permitted the redistribution of their matter, the great
majority remain much nearer to the surface of the earth. The matter of the
different subdivisions of that world interpenetrates with perfect freedom,
but there is on the whole a general tendency for the denser matter to
settle towards the centre. The conditions are much like those which obtain
in a bucket of water which contains in suspension a number of kinds of
matter of different degrees of density. Since the water is kept in
perpetual motion, the different kinds of matter are diffused through it;
but in spite of that, the densest matter is found in greatest quantity
nearest to the bottom. So that though we must not at all think of the
various subdivisions of the astral world as lying above one another as do
the coats of an onion, it is nevertheless true that the average arrangement
of the matter of those subdivisions partakes somewhat of that general
character.

Astral matter interpenetrates physical matter precisely as though it were
not there, but each subdivision of physical matter has a strong attraction
for astral matter of the corresponding subdivision. Hence it arises that
every physical body has its astral counterpart. If I have a glass of water
standing upon a table, the glass and the table, being of physical matter in
the solid state, are interpenetrated by astral matter of the lowest
subdivision. The water in the glass, being liquid, is interpenetrated by
what we may call astral liquid--that is, by astral matter of the sixth
subdivision; whereas the air surrounding both, being physical matter in the
