But for one entity who is earth-bound by the desire to communicate with his surviving friends, there are thousands who, if left alone, would never think of doing so, although when the idea is suggested to them through a medium they will respond to it readily enough, for since during earth-life their interests were probably centred less in spiritual than in worldly affairs, it is not difficult to re-awaken in them vibrations sympathetic to matters connected with the existence they have so lately left; and this undesirable intensification of earthly thoughts is frequently brought about by the interference of well-meaning but ignorant friends, who endeavour to get communications from the departed through a medium, with the result that just in proportion to their success he is subjected to the various dangers mentioned above. It should also be remembered that the possible injury to the entity itself is by no means all the harm that may accrue from such a practice, for those who habitually attend _seances_ during life are almost certain to develop a tendency to haunt them after death, and so themselves in turn run the risks into which they have so often brought their predecessors. Besides, it is well known that the vital energy necessary to produce physical manifestations is frequently drawn from the sitters as well as from the medium, and the eventual effect on the latter is invariably evil, as is evinced by the large number of such sensitives who have gone either morally or psychically to the bad--some becoming epileptic, some taking to drink, others falling under influences which induced them to stoop to fraud and trickery of all kinds. 4. _The Shade._
