Practical Psychomancy & Crystal Gazing By William Walker Atkinson

William Walker Atkinson’s lesson-based manual explores crystal gazing, psychometry and what he calls psychic sensing. Topics include concentration, visualization, interpreting impressions, astral projection and experiences associated with dreams or distant events.

For readers of historical divination and psychic-development literature. This is a book about these practices, not a crystal set or a scientific validation of psychic abilities.
