Understand and Develop Your ESP
BASED ON THE EDGAR CAYCE READINGS
by Mark A. Thurston, Ph.D.
ACKNOWLEDGEMENTS
The author wishes to acknowledge the invaluable help provided by Charles Thomas
Cayce in the preliminary steps of writing this book. That work involved reading
together all of the material Edgar Cayce gave on psychic ability and discussing
its possible meaning and implications.
In addition, a special thanks is due Doris Dean and Diana Reed for their work
in the preparation of the text. Finally, the author wishes to thank Bob Smith
for editing the text. The original version of this book (used as an instruction
manual for research purposes) was overly technical and more difficult to read.
Bob has a special gift for making a complex subject more easily understandable,
and his work on this book has been particularly helpful.
