icular brain-mind unit (the same muscles that
reflexively _express_ the ideas of that one part of your multiplex ego)
you may be absolutely _sure_ of developing a particular related
characteristic. For example, if you want to sharpen your _perceptive_
faculties so that you will see with the _eyes of your mind_ much more
than the _ordinary_ man perceives, exercise your _physical_ eyes in
taking snap-shots that you can see clearly in detail _with your

your eyes. The reality will be very different from your imagined
picture. But _sharpen your perceptive faculties_, develop a "camera

in court often contradict one another, in all honesty, simply because
their ability to perceive actualities is not highly developed. In
consequence, they get false mental impressions of happenings or things

[Sidenote: Three Processes Of Mental Development]

There are but three _processes_ of mental development:

The first process comprises _getting information_ from a _sense_ to its
associated _brain center_, which then makes the _mind_ center conscious
that particular information has been transmitted to it.

The second process is _organizing_ the information in the mind center,
with relation to _other_ information _previously_ brought to the mind.

In the third process the mind center directs its co-related brain center
to send out certain _impulses of action_ to the corresponding muscular
structure.

Let us analyze an illustration of these three processes of mental
development. Suppose first you _hear_ something that concerns a
particular prospect for your "goods of sale." Second, you comprehend the
_significance_ to you of what you have heard. Third, your mind directs
your muscles to make a par
