But it is not necessary to exercise the imagination in the direction of picturing beings on other planets endowed with more senses than have the people of earth. While, as the occult teachings positively state, there are beings on other planets whose senses are as much higher than the earth-man's as the latter's are higher than those of the oyster, still we do not have to go so far to find instances of the possession of much higher and more active faculties than those employed by the ordinary man. We have but to consider the higher psychical faculties of man, right here and now, in order to see what new worlds are open to him. When you reach a scientific understanding of these things, you will see that there really is nothing at all supernatural about much of the great body of wonderful experiences of men in all times which the "horse sense" man sneeringly dismisses as "queer" and "contrary to sense." You will see that these experiences are quite as natural as are those in which the ordinary five senses are employed--though they are super-physical. There is the greatest difference between supernatural and super-physical, you must realize. All occultists know that man has other senses than the ordinary five, although but few men have developed them sufficiently well to use them effectively. These super-physical senses are known to the occultists as "the astral senses." The term "Astral," used so frequently by all occultists, ancient and modern, is derived from the Greek word "astra," meaning "star." It is used to indicate those planes of being immediately above the physical plane. The astral senses are really the counterparts of the physical senses of man, and are connected with the astral body of the person just as the physical senses are connected with the physical body. The office of these astral senses is to enable the person to receive impressions on the astral plane, just as his physical senses enable him to receive impressions on the physical plane. On the physical plane the mind of man receives only the sense impressions of the physical organs of sense; but when the mind functions and vibrates on the astral plane, it requires astral senses in order to receive the impressions of that plane, and these, as we shall see, are present. Each one of the physical senses of man has its astral counterpart. Thus man has, in latency, the power of seeing, feeling, tasting, smelling, and hearing, on the astral plane, by means of his five astral senses. More than this, the best occultists know that man really has seven physical senses instead of but five, though these two additional senses are not unfolded in the case of the average person (though occultists who have reached a certain stage are able to use them effectively). Even these two extra physical senses have their counterparts on the astral plane.
