al' excitement or fervor."

These things being perceived, and recognized as true, the next question
that presents itself to the mind of the intelligent student is this: "But
what causes the difference in power and effect between the thought and
feeling-vibrations of different persons?" This question is a valid one,
and arises from a perception of the underlying variety and difference in
the thought vibrations of different persons. The difference, my students,
is caused by three principal facts, viz., (1) difference in degree of
feeling; (2) difference in degree of visualization; and (3) difference in
degree of concentration. Let us examine each of these successively, so as
to get at the underlying principle.

The element of emotional feeling is like the element of fire in the
production of steam. The more vivid and intense the feeling or emotion,
the greater the degree of heat and force to the thought wave or vibratory
stream projected. You will begin to see why the thought vibrations of
those animated and filled with strong desire, strong wish, strong
ambition, etc., must be more forceful than those of persons of the
opposite type.

The person who is filled with a strong desire, wish or ambition, which has
been fanned into a fierce blaze by attention, is a dynamic power among
other persons, and his influence is felt. In fact, it may be asserted that
as a general rule no person is able to influence men and things unless he
have a strong desire, wish or ambition within him. The power of desire is
a wonderful one, as all occultists know, and it will accomplish much even
if the other elements be lacking; while, in proper combination with other
principles it will accomplish wonders. Likewise, a strong interest in a
thing will cause a certain strength to the thought-vibrations connected
therewith. Interest is really an emotional feeling, though we generally
think of it as merely something connected with the intellect. A cold
intellectual thought has very little force, unless backed up by strong
interest and concentration. But any intellectual thought backed up with
interest, and focused by concentration, will produce very strong thought
vibrations, with a marked inductive power.

Now, let us consider the subject of visualization. Every person knows that
the person who wishes to accomplish anything, or who expects to do good
work along any line, must first know what he wishes to accomplish. In the
degree that he is able to
