different levels of nature, and he is therefore
provided with a suitable vehicle of the matter
belonging to each, and it is through these various
vehicles that he is able to receive impressions
from the worlds to which they correspond.
We must not think of the man as creating
these vehicles for himself in the course of his
future evolution, for every man possesses them
from the beginning, though he is by no means
conscious of their existence. We are constantly
using to a certain extent this higher matter
within ourselves, even though it be uncon-
sciously. Every time that we think, we set in
motion the mental matter within us, and a
thought is clearly visible to a clairvoyant as a
vibration in that matter, set up first of all
within the man, and then affecting matter of
the same degree of density in the world around
him. But before this thought can be effective

from that mental matter into astral matter; and

the astral matter in its turn affects the etheric
matter, creating sympathetic vibrations in it,

matter, the grey matter of the brain.
