see the thing in his mind's eye--to picture the
thing in his imagination--in that degree will he tend to manifest the
thing itself in material form and effect.

Sir Francis Galton, an eminent authority upon psychology, says on this
point: "The free use of a high visualizing faculty is of much importance
in connection with the higher processes of generalized thought. A visual
image is the most perfect form of mental representation wherever the
shape, position, and relations of objects to space are concerned. The best
workmen are those who visualize the whole of what they propose to do
before they take a tool in their hands. Strategists, artists of all
denominations, physicists who contrive new experiments, and, in short, all
who do not follow routine, have need of it. A faculty that is of
importance in all technical and artistic occupations, that gives accuracy
to our perceptions and justice to our generalizations, is starved by lazy
disuse instead of being cultivated judiciously in such a way as will, on
the whole, bring best return. I believe that a serious study of the best
way of developing and utilizing this faculty, without prejudice to the
practice of abstract thought in symbols, is one of the pressing desirata
in the yet unformed science of education."

Not only on the ordinary planes is the forming of strong mental images
important and useful, but when we come to consider the phenomena of the
astral plane we begin to see what an important part is played there by
strong mental images or visualized ideas. The better you know what you
desire, wish or aspire to, the stronger will be your thought vibrations of
that thing, of course. Well, then, the stronger that you are able to
picture the thing in your mind--to visualize it to yourself--the stronger
will be your actual knowledge and thought-form of that thing. Instead of
your thought vibrations being grouped in nebulous forms, lacking shape and
distinct figure, as in the ordinary case; when you form strong, clear
mental images of what you desire or wish to accomplish, then do the
thought vibrations group themselves in clear, strong distinct forms. This
being done, when the mind of other persons are affected by induction they
get the clear idea of the thought and feeling in your mind, and are
strongly influenced thereby.

A little later on, I shall call your attention to the Attractive Power of
Thought. But at this point I wish to say to you that while thought
