by another person whose feelings are not friendly to him, no matter how
friendly the outward appearance of that person may be. These two extra
senses co-operate to give a person that instinctive feeling of warning,
which all of us know in our own experience.

This particular, as well as the telepathic sense, may be cultivated or
developed by anyone who wishes to take the time and trouble to accomplish
the work. The principle is simple--merely the same principle that one uses
in developing any of the other physical attributes, namely, use and
exercise. The first step (a) is the recognition of the existence of the
sense itself; then (b) the attention given to its reports; then (c)
frequent use and exercise. Just think of how you would proceed to develop
any of the five ordinary senses--the hearing, sight, or touch, for
instance--then follow the same process in the cultivation of this extra
sense, or two senses, and you will accomplish the same kind of results.

Now, let us consider the other extra physical sense--the "telepathic"
sense, or sense of becoming aware of the thought-waves, or emotional
waves, of other persons. Now, as strange as this may appear to some
persons--the most of persons in fact--this telepathic faculty is not a
"higher" faculty or sense, but is really a comparatively low one. Just
like the sense just described, it is possessed in a higher degree by many
of the lower animals, and by primitive and savage man. That which really
is "higher" in this kind of psychic phenomena is the manifestation of that
higher form of telepathy--by use of the astral counterpart of this
sense--which we shall consider, later, under the name of clairvoyance, for
this is really a particular phase of clairvoyance.

As strange as it may appear to some of you, the lower animals possess a
kind of telepathic sense. An animal is usually aware of your feelings
