Clairaudience is far more general than second sight, but there is the same variability in the range of perception as is seen in clairvoyance and psychometry. Thus while one hears only the evil suggestions of "obsessing spirits" or discarnate souls being dinned into his ears, another will be lifted to the third heaven and hear "things unutterable." Brain-cell discharges will hardly account for the phenomena of clairaudience. A brain-cell discharge never goes beyond the repetition of one's own name in some familiar voice, or at most the revival of a phrase or the monotonous clang of a neighbouring church bell. These are not clairaudiences at all. Clairaudience consists in receiving auditory impressions of intelligible phrases not previously associated with the name of person or place involved in the statement. These impressions may be sporadic or may be continuous. In the case of a genuine development where the interior sense is fully opened up, the communication will be continuous and normal, as much so as ordinary conversation, and the translation of consciousness into terms of sense will be so rapid and unimpeded as to give the impression to an Englishman that he is listening to his native language and to a Frenchman that he is listening to French, though the communication may proceed from a source which renders this impossible. The universal language of humanity is neither Volapuk, nor Esperanto, nor Ido. It is Thought, and when thought proceeds from a point beyond the plane of differentiation it can be determined along the line which makes for English as readily as that which makes for French, or any other tongue. It is they of the soul-world who convey the thought, it is we of the sublunary world who translate that thought into our own language. The Hebrew prophets were almost uniformly instructed by means of clairaudience. But as I have already said there are degrees of clairaudience, as of any other psychic faculty. The danger is that a false value may be set upon the experiences, especially during the early stages of development when everything is very new and very wonderful.
