Many spiritual mediums of the present day have the faculty largely developed. Some of them are enabled to obtain the names of their sitters by hearing them spoken clairaudiently, and the names of supposed spirits are obtained in the same way. It is popularly supposed that the ordinary method of telepathic communion, when the message is not brought above the threshold of consciousness, is by mental impressions. It is, of course, impossible for us to know the processes employed in the ordinary communion of subjective minds. It seems probable, however, that it is by means of such language as is employed by the communicants in objective life. All that is or can be known is, that when the ideas are communicated to the conscious mind, it is necessarily by such means as can be understood,--that is, by means which appeal to the senses. It is true that the subjective mind is often able strongly to impress the objective mind, especially when danger to the person is imminent, or when some near relative or dear friend is in danger. Such impressions are known as premonitions. Sometimes they are so strong as to be of real service in averting danger. But they are not always reliable, for the reason that we are seldom able to distinguish a real premonition from that feeling arising from fear and anxiety regarding the welfare of those who are absent and very dear to us. Thus, a mother will often feel that she has a premonition of danger to an absent child, but will afterwards learn that her fears were groundless. Perhaps at another time a real premonition will be disregarded. It seems probable that when the laws of subjective mental action are better understood, there may be some method formulated by which a genuine premonition may be recognized. It is certain that in all cases where danger to the person is imminent, the subjective mind makes a supreme effort to give warning and avert the danger. That being its normal function, its highest activity is exercised in the effort to preserve the life of the individual. It is sometimes successful, and sometimes not; but that the effort is always made does not admit of doubt. Sometimes it succeeds by means most extraordinary,--clairaudience not infrequently being the means of receiving the warning. Thus, a lady once confessed to the writer that she at one time, in a fit of despondency arising from ill health, attempted to commit suicide. She had raised a pistol to her head and was about to fire, when she heard an explosive sound, apparently in the same room, resembling a pistol-shot. This caused her to pause for an instant, when she heard the words, apparently spoken in her ear, "Not now; you have two years yet!" Surprise caused her to lower the pistol, and reflection caused her to desist, and finally to abandon the idea of suicide. As the two years have not yet expired, it is too early to know whether it is a case of prevision as well as of clairaudience.
