Genuine Mediumship Or the Invisible Powers

The moment that there appears any manifestation which is possible of being known to, or experienced by, the human senses, ordinary or extraordinary, that moment the phenomena and the immediate cause thereof must be regarded as being properly classed in the category of "natural." This is true not only of such phenomena as are perceived by means of our ordinary five senses, but also of those which are perceptible only to the highest powers of perception, or higher senses, which are latent in all human beings but which are unfolded only in the case of a comparatively few individuals of the race.
