Clairvoyance [EPUB ebook] 

Clairvoyance means literally nothing more than ‘clear-seeing, ‘ and it is a word which has been sorely misused, and even degraded so far as to be employed to describe the trickery of a mountebank in a variety show. Even in its more restricted sense it covers a wide range of phenomena, differing so greatly in character that it is not easy to give a definition of the word which shall be at once succinct and accurate. It has been called ‘spiritual vision, ‘ but no rendering could well be more misleading than that, for in the vast majority of cases there is no faculty connected with it which has the slightest claim to be honoured by so lofty a name.
This book is your guide into the world and secrets of clairvoyance.
