the work of this plane of the
mind. They have given us full and ingenious theories and examples of the
workings of the Instinctive Mind, and in some cases they have touched
upon the workings and operations of the Intuitional planes, but in nearly
every case they have treated the Intellect as something entirely confined
to the Conscious plane of mentation. In this they have missed some of the
most interesting and valuable manifestations of sub-conscious mentation.

In this lesson we will take up this particular phase of mentation, and
trust to be able to point out the way to use it to the best advantage,
giving some simple instructions that have been given by the Hindu
teachers to their students for centuries past, such instructions of
course, being modified by us to conform to the requirements and
necessities of the Western student of today.

We have taken the liberty of bestowing a new title upon this phase of
mentation--we have thought it well to call it "Sub-consciousing." The
word "Sub," of course means "under; below;" and the word "Consciousing"
is a favorite term employed by Prof. Elmer Gates, and means receiving
impressions from the mind. In a general way, "Sub-consciousing," as used
in this lesson, may be understood to mean "using the subconscious mind,
under orders of the conscious mind."

By referring to our Eighth Lesson, we see mention made of the case of the
man who indulged in "unconscious rumination," which happened to him when
he read books presenting new points of view essentially opposed to his
previous opinion. You will note that after days, weeks, or months, he
found that to his great astonishment the old opinions were entirely
rearranged, and new ones lodged there.

On the same page you will see mentioned the case of Sir William Hamilton,
who discovered an important law of mathematics while walking with his
wife. In this case he had been previously thinking of the missing link in
his chain of reasoning, and the problem was worked out for him by the
sub-conscious plane of his Intellect.

On the same page, and the one following, is found the case of Dr.
Thompson, who gives an interesting account of the workings of this part
of his mind, which caused him at times to experience a feeling of the
uselessness of all voluntary effort, coupled with a feeling that the
matter was working itself clear in his mind. He tells us that at times he
seemed to be merely a passive instrument in the hands of some pe
