The second phase of Psychic Influence is that called Distant Psychic Influence, in which psychic induction is manifested when the persons are distant in space from one another--not in the presence of each other. Here, of course, we see the principle of telepathy involved in connection with the process of mental induction: and in some cases even the astral telepathic sense is called into operation. The student who has followed my explanation and course of reasoning in the preceding lessons will readily perceive that the principle involved in this distant phase of psychic influence is precisely the same as that employed in direct personal psychic influence. As I have explained in an early lesson, it matters little whether the space to be covered by the psychic vibratory waves is but one foot or a thousand miles, the principle is exactly the same. There are, of course, other principles involved in the case of two persons meeting face to face and calling into force their psychic powers; for instance, there is the element of suggestion and association, and other psychological principles which are not in force when the two persons are out of the actual presence of each other. But so far as the telepathic or astral psychic powers are concerned, the mere extension of space does not change the principle. The student who has developed his power of psychic induction in the phases mentioned in the preceding chapter, may begin to experiment and practice psychic induction at long-range, if he so wishes. That is to say, instead of causing psychic induction in the minds of persons actually in his presence and sight, he may produce similar results in persons out of his sight and presence. The person may be brought into presence and psychic contact, for all practical purposes, by using the visualizing powers for the purpose of bringing him into the en rapport condition. That is to say, by using the imagination to bring into the mind a strong clear picture of the other person, you may induce an en rapport condition in which he will be practically in the same psychic relation to you as if he were actually before you. Of course, if he is sufficiently well informed regarding occult matters, he may shut you out by drawing a psychic circle around himself which you cannot penetrate, or by surrounding himself with psychic armor or atmosphere such as I have already mentioned in preceding lessons. But as he will not likely know anything of this, the average person may be reached in the manner just mentioned. Or again, you may establish en rapport conditions by psychometric methods, by holding to your forehead an article which has been in the other person's possession for some time; an article worn by him; a piece of his hair; etc. Or, again, you may use the crystal to bring up his astral vision before you. Or, again, you may erect an "astral tube" such as I will mention a little further on in this chapter, and thus establish a strong en rapport condition.
