Swami Panchadasi 
Clairvoyance and Occult Powers [PDF ebook] 

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. I must, however, positively and firmly state that while these cases and illustrations, these quotations and citations, are purely Western, the principles they illustrate and prove are among the oldest known to Hindu occult science and philosophy. In fact, having been accepted as proven truth in India, for centuries past, there is very little demand for further proof thereof on the part of the Hindus. In the Western world, however, these things are comparatively new, and must be proved and attested accordingly.
