want; only with the knowledge that the true self includes the inner and
higher self which is always in immediate touch with the Great Divine Mind.

As Walt Whitman says:--"You are not all included between your hat and your
boots."

_The growing popularity of the Edinburgh Lectures on Mental Science has led
me to add to the present edition three more sections on Body, Soul, and
Spirit, which it is hoped will prove useful by rendering the principles of
the interaction of these three factors somewhat clearer_.

THE BODY.


Some students find it difficult to realize that mental action can produce
any real effect upon material substance; but if this is not possible there
is no such thing as Mental Science, the purpose of which is to produce
improved conditions both of body and environment, so that the ultimate
manifestation aimed at is always one of demonstration upon the plane of the
visible and concrete. Therefore to afford conviction of an actual
connection between the visible and the invisible, between the inner and the
outer, is one of the most important points in the course of our studies.
