The agent most suitable for developing clairvoyance cannot therefore be definitely prescribed. It must remain a matter of experiment with the subject himself. That there are some persons in whom the psychic faculties are more prone to activity than in others is certain, and it would appear also that these faculties are native in some by spiritual or hereditary succession, which fact is evident from their genitures as interpreted by astrology. Many planets in flexed signs and a satellitium in the nadir or lower angle of the horoscope is a certain indication of extreme nervous sensibility and predisposition to telaesthenic impressions, though this observation does not cover all the instances before me. It is true, however, where it applies. The dominant influence of the planet Neptune in a horoscope is also to be regarded as a special indication of some form of psychic activity, as I have frequently observed. In cases where the subject is not prepared by evolutional process for the exercise of the psychic faculties, it will be found that the same or similar indications will tend to the simulation of such faculties, as by mediumism, conjuring, etc., while they may even result in chicanery and fraud. But among those who are gifted in the direction spoken of, all are not clairvoyant. The most common form of psychic disturbance is involuntary clairaudience, and telaesthesia is not perhaps less general. St. Paul indicates a variety of such psychic "gifts," _e.g._ the gifts of prophecy, of healing, of understanding, etc.; but these may also be regarded in quite a mundane sense. The development among the early Christians of spiritual gifts, visions, hearing, speaking in foreign tongues, psychic healing, etc., appears to have given rise to a variety of exceptional experiences by which they were induced to say "we cannot but speak the things we have seen and heard." "One star differs from another in glory," says St. Paul, and this diversity of spiritual gifts proceeds from the celestial world, and is so ordered that each may fulfil the part required of him in the economy of life.
