Another, and a most peculiar, phase of space clairvoyance is that in which certain persons so awaken the astral senses of other persons that these persons perceive the first person—usually in the form of seemingly seeing the person present in the immediate vicinity, just as one would see a ghostly visitor. In some cases there is manifested double-clairvoyance, both persons visioning clairvoyantly; in other cases, only the person "visited" astrally senses the occurrence. The following cases illustrate this form of space clairvoyance.

W.T. Stead relates the case of a lady well known to him, who spontaneously developed the power of awakening astral perception in others. She seemed to "materialize" in their presence. Her power in this direction became a source of considerable anxiety and worry to her friends to whom she would pay unexpected and involuntary visits, frightening them out of their wits by the appearance of her "ghost." They naturally thought that she had died suddenly and had appeared to them in ghostly form. The lady, her self, was totally unconscious of the appearance, though she admitted that at or about the times of the appearances she had been thinking of her friends whom she visited astrally.

The German writer, Jung Stilling, mentions the case of a man of good character who had developed power of this kind, but also was conscious of his visits. He exerted the power consciously by an effort of will, it seems. At one time he was consulted by the wife of a sea captain whose husband was on a long voyage to Europe and Asia (sailing from America). His ship was long overdue, and his wife was quite worried about him. She consulted the gentleman in question, and he promised to do what he could for her. Leaving the room he threw himself on a couch and was seen by the lady (who peered through the half-opened door) to be in a state of semi-trance. Finally he returned and told her that he had visited her husband in a coffee-house in London, and gave her husband's reasons for not writing, adding that her husband would soon return to America. When her husband returned several months later, the wife asked him about the matter. He informed her that the clairvoyant's report was correct in every particular. Upon being introduced to the clairvoyant, the captain manifested great surprise, saying that he had met the man in question on a certain day in a coffee-house in London, and that the man had told him that his wife was worried about him, and that he had told the man that he had been prevented from writing for several reasons, and that he was on the eve of beginning his return voyage to America. He added that when he looked for the man a few moments afterwards, the stranger had apparently lost himself in the crowd, disappeared and was seen no more by him.

The Society for Psychical Research gives prominence to the celebrated case of the member of the London Stock Exchange, whose identity it conceals under the initials "S.H.B.," who possessed this power of voluntary awakening of astral sight in others by means of his "appearance" to them. The man relates his experience to the Society as follows: "One Sunday night in November, 1881, I was in Kildare Gardens, when I willed very strongly that I would visit in the spirit two lady friends, the Misses X., who were living three miles off, in Hogarth Road. I willed that I should do this at one o'clock in the morning, and having willed it, I went to sleep. Next Thursday, when I first met my friends, the elder lady told me that she woke up and saw my apparition advancing to her bedside. She screamed and woke her sisters, who also saw me." (The report includes the signed statement of the ladies, giving the time of the appearance, and the details thereof.)

"Again, on December 1, 1882, I was at Southall. At half-past nine I sat down to endeavor to fix my mind so strongly upon the interior of a house at Kew, where Miss V. and her sister lived, that I seemed to be actually in the house. I was conscious, but was in a kind of mesmeric sleep. When I went to bed that night, I willed to be in the front bedroom of that house at Kew at twelve; and to make my presence felt by the inmates. Next day I went to Kew. Miss V.'s married sister told me, without any prompting from me, that she had seen me in the passage going from one room to another at half-past nine o'clock, and that at twelve, when she was wide awake, she saw me come to the front bedroom, where she slept, and take her hair, which is very long, into my hand. She said I then took her hand, and gazed into the palm intently. She said, 'You need not look at the lines, for I never have any trouble.' She then woke her sister. When Mrs. L. told me this, I took out the entry that I had made the previous night and read it to her. Mrs. L. is quite sure she was not dreaming. She had only seen me once before, two years previously. Again, on March 22, 1884, I wrote to Mr. Gurney, of the Psychical Research Society, telling him that I was going to make my presence felt by Miss V., at 44 Norland Square, at midnight. Ten days afterwards, I saw Miss V., when she voluntarily told me that on Saturday at midnight, she distinctly saw me, when she was quite wide awake."

The records of the psychic researchers are filled with numerous accounts of cases in which similar astral projections have occurred when the person was on his or her death-bed, but was still alive. It would seem that under such circumstances the astral senses are very much freer from the interference of the physical senses, and tend to manifest very strongly in the form of appearances to persons in whom the dying person is attached by the ties of affection. Many who read this course have known of cases of this kind, for they are of quite frequent occurrence.

The student will notice that in the majority of the cases cited in this chapter the clairvoyant has been in a state of sleep, or semi-sleep—often in a dream condition. But you must not jump to the conclusion that this condition is always necessary for the manifestation of this phenomenon. On the contrary, the advanced and well developed clairvoyants usually assume merely a condition of deep reverie or meditation, shutting out the sounds and thoughts of the physical plane, so as to be able to function better on the astral plane.

The reason that so many recorded cases have occurred when the clairvoyant person was asleep, and the vision appeared as a dream, is simply because in such a condition the physical senses of the person are stilled and at rest, and there is less likelihood of interference from them, and a better opportunity for the astral senses to function effectively. It is like the familiar cases in which one becomes so wrapped up in viewing a beautiful work of art, or in listening to a beautiful musical rendition, that he or she forgets all about the sights and sounds of the world outside. One sometimes gets into this same condition when reading an interesting book, or when witnessing an interesting play. When the psychic powers are concentrated upon any one channel of vision, the others fail to register a clear impression. The same rule holds good on the astral plane, as on the physical.

There are certain psychic conditions which are especially conducive to the manifestation of clairvoyant phenomena, as all students of the subject know very well. These conditions are somewhat hard to induce, at least until the clairvoyant has had considerable experience and practice. But, in the state of sleep, the person induces the desired conditions, in many cases, though he is not consciously doing so. As might naturally be expected, therefore, the majority of the recorded cases of clairvoyance have occurred when the clairvoyant person has been asleep.

I should also state, once more, that in many cases in which the clairvoyant has witnessed the "appearance" of another person, as in the cases such as I have just mentioned, there is always the possibility of the person having actually appeared in his astral body, unconsciously to himself of course. No one but a skilled occultist is able to distinguish between cases of this kind. The line between this class of clairvoyance and astral appearance is very thin, and, in fact, the two classes of phenomena shade and blend into each other. In reality, when one gets down to bottom principles, there is very little difference between the actual appearance in the astral body, and the strong projection of one's presence by means of will, conscious or unconscious, along the lines of awakening the clairvoyant vision of others. To attempt to explain the slight points of difference here, would only involve the student in a mass of technical description which would tend to confuse, rather than to enlighten him—from this I refrain.
