Students of Theosophical literature are well aware that there are such teachers to be found—that even in this materialistic nineteenth century the old saying is still true, that "when the pupil is ready, the Master is ready also," and that "in the hall of learning, when he is capable of entering there, the disciple will always find his Master." They are well aware also that only under such guidance can a man develop his latent powers in safety and with certainty, since they know how fatally easy it is for the untrained clairvoyant to deceive himself as to the meaning and value of what he sees, or even absolutely to distort his vision completely in bringing it down into his physical consciousness.
It does not follow that even the pupil who is receiving regular instruction in the use of occult powers will find them unfolding themselves exactly in the regular order which was suggested above as probably ideal. His previous progress may not have been such as to make this for him the easiest or most desirable road; but at any rate he is in the hands of one who is perfectly competent to be his guide in spiritual development, and he rests in perfect contentment that the way along which he is taken will be that which is the best way for him.
Another great advantage which he gains is that whatever faculties he may acquire are definitely under his command and can be used fully and constantly when he needs them for his Theosophical work; whereas in the case of the untrained man such powers often manifest themselves only very partially and spasmodically, and appear to come and go, as it were, at their own sweet will.
It may reasonably be objected that if clairvoyant faculty is, as stated, a part of the occult development of man, and so a sign of a certain amount of progress along that line, it seems strange that it should often be possessed by primitive peoples, or by the ignorant and uncultured among our own race—persons who are obviously quite undeveloped, from whatever point of view one regards them. No doubt this does appear remarkable at first sight but the fact is that the sensitiveness of the savage or of the coarse and vulgar European ignoramus is not really at all the same thing as the faculty of his properly trained brother, nor is it arrived at in the same way.
An exact and detailed explanation of the difference would lead us into rather recondite technicalities, but perhaps the general idea of the distinction between the two may be caught from an example taken from the very lowest plane of clairvoyance, in close contact with the denser physical. The etheric double in man is in exceedingly close relation to his nervous system, and any kind of action upon one of them speedily reacts on the other. Now in the sporadic appearance of etheric sight in the savage, whether of Central Africa or of Western Europe, it has been observed that the corresponding nervous disturbance is almost entirely in the sympathetic system, and that the whole affair is practically beyond the man's control—is in fact a sort of massive sensation vaguely belonging to the whole etheric body, rather than an exact and definite sense-perception communicated through a specialized organ.
As in later races and amid higher development the strength of the man is more and more thrown into the evolution of the mental faculties, this vague sensitiveness usually disappears; but still later, when the spiritual man begins to unfold, he regains his clairvoyant power. This time, however, the faculty is a precise and exact one, under the control of the man's will, and exercised through a definite sense-organ; and it is noteworthy that any nervous action set up in sympathy with it is now almost exclusively in the cerebro-spinal system.
On this subject Mrs. Besant writes:—"The lower forms of psychism are more frequent in animals and in very unintelligent human beings than in men and women in whom the intellectual powers are well developed. They appear to be connected with the sympathetic system, not with the cerebro-spinal. The large nucleated ganglionic cells in this system contain a very large proportion of etheric matter, and are hence more easily affected by the coarser astral vibrations than are the cells in which the proportion is less. As the cerebro-spinal system develops, and the brain becomes more highly evolved, the sympathetic system subsides into a subordinate position, and the sensitiveness to psychic vibrations is dominated by the stronger and more active vibrations of the higher nervous system. It is true that at a later stage of evolution psychic sensitiveness reappears, but it is then developed in connection with the cerebro-spinal centres, and is brought under the control of the will. But the hysterical and ill-regulated psychism of which we see so many lamentable examples is due to the small development of the brain and the dominance of the sympathetic system."
Occasional flashes of clairvoyance do, however, sometimes come to the highly cultured and spiritual-minded man, even though he may never have heard of the possibility of training such a faculty. In his case such glimpses usually signify that he is approaching that stage in his evolution when these powers will naturally begin to manifest themselves, and their appearance should serve as an additional stimulus to him to strive to maintain that high standard of moral purity and mental balance without which clairvoyance is a curse and not a blessing to its possessor.
Between those who are entirely unimpressible and those who are in full possession of clairvoyant power there are many intermediate stages. One to which it will be worth while to give a passing glance is the stage in which a man, though he has no clairvoyant faculty in ordinary life, yet exhibits it more or less fully under the influence of mesmerism. This is a case in which the psychic nature is already sensitive, but the consciousness is not yet capable of functioning in it amidst the manifold distractions of physical life. It needs to be set free by the temporary suspension of the outer senses in the mesmeric trance before it can use the diviner faculties which are but just beginning to dawn within it. But of course even in the mesmeric trance there are innumerable degrees of lucidity, from the ordinary patient who is blankly unintelligent to the man whose power of sight is fully under the control of the operator, and can be directed whithersoever he wills, or to the more advanced stage in which, when the consciousness is once set free, it escapes altogether from the grasp of the magnetizer, and soars into fields of exalted vision where it is entirely beyond his reach.
Another step along the same path is that upon which such perfect suppression of the physical as that which occurs in the hypnotic trance is not necessary, but the power of supernormal sight, though still out of reach during waking life, becomes available when the body is held in the bonds of ordinary sleep. At this stage of development stood many of the prophets and seers of whom we read, who were "warned of God in a dream," or communed with beings far higher than themselves in the silent watches of the night.
