"astral perception," as distinguished from perception by means of the
physical senses. As we proceed, you will see the general and special
meanings of the term, so there is no necessity for a special definition or

By "telepathy," I mean the sending and receiving of thought messages, and
mental and emotional states, consciously or unconsciously, by means of
what may be called "the sixth sense" of the physical plane. There is, of

explained later on.

You will remember that in the preceding chapter I told you that in
addition to the five ordinary physical senses of man there were also two
other physical senses comparatively undeveloped in the average person.
These two extra physical senses are, respectively, (1) the sense of the
presence of other living things; and (2) the telepathic sense. As I also
told you, these two extra physical senses have their astral counterparts.
They also have certain physical organs which are not generally recognized
by physiologists or psychologists, but which are well known to all
occultists. I shall now consider the first of the two above-mentioned
extra physical senses, in order to clear the way for our consideration of
the question of the distinction between ordinary telepathy and that form
of clairvoyance which is its astral counterpart.

There is in every human being a sense which is not generally recognized as
such, although nearly every person has had more or less experience
regarding its workings. I refer to the sense of the presence of other
living things, separate and apart from the operation of any of the five
ordinary physical senses. I ask you to understand that I am not claiming
