This workbook is intended as an experiential guide to the ancient art of alchemy. The principles revealed here are based on many centuries of alchemical practice and date back to a time when some of the most creative minds in the world delved into the intertwined mysteries of matter and energy, soul and spirit. Those philosophers of nature sought universal laws of transformation that were as valid in their laboratory experiments as they were in their own hearts and minds. Their legacy to us is an amazing spiritual technology that works on all levels at once, a powerful Science of Soul whose principles are as valid in the physical world as they are in the psychological and spiritual realms.
