was, and how it was independent of the material coverings, etc. But there
is still another step in this self analysis--a more difficult step. Even
when the Candidate has awakened to a realization of his independence of
the body, and material coverings, he often confounds the "I" with the
lower principles of the mind. This is a mistake. The Mind, in its various
phases and planes, is but a tool and instrument of the "I," and is far
from being the "I" itself. We shall try to bring out this fact in this
lesson and its accompanying exercises. We shall avoid, and pass by, the
metaphysical features of the case, and shall confine ourselves to the
Yogi Psychology. We shall not touch upon theories, nor attempt to
explain the cause, nature and purpose of the Mind--the working tool of
the Ego--but instead shall attempt to point out a way whereby you may
analyze the Mind and then determine which is the "not I" and which is the
real "I." It is useless to burden you with theories or metaphysical talk,
when the way to prove the thing is right within your own grasp. By using
the mind, you will be able to separate it into its parts, and force it to
give you its own answer to the questions touching itself.

In the second and third lessons of our "_Fourteen Lessons_," we pointed
out to you the fact that man had three Mental Principles, or subdivisions
of mind, all of which were below the plane of Spirit. The "I" is Spirit,
but its mental principles are of a lower order. Without wishing to unduly
repeat ourselves, we think it better to run hastily over these three
Principles in the mind of Man.

First, there is what is known as the Instinctive Mind, which man shares
in common with the lower animals. It is the first principle of mind that
appears in the scale of evolution. In its lowest phases, consciousness
is but barely perceptible, and mere sensation is apparent. In its higher
stages it almost reaches the plane of Reason or Intellect, in fact, they
