Know Thy Self was the Ancient Greek aphorism inscribed in the forecourt of the Temple of Apollo at Delphi. If this maxim deserves the importance ascribed to it over the centuries, then the Ancient Science of the Cards is surely of great potential significance, for it can vastly aid us in understanding ourselves, as well as our relations with others. Apart from our basic need for food, shelter, and sustenance, our most consuming preoccupation is our relations with our fellow human beings. We're concerned with how we can get along better with others, how we can tell which people are trustworthy, with whom we can form productive relationships or conduct business negotiations, and to whom we can entrust our health and finances. We're particularly interested in finding the perfect mate and other questions that hinge on our chemistry or compatibility with other people. The Ancient Science of the Cards can answer many of these questions at a glance, with just a few arithmetical calculations and a bit of interpretation. Stefan G. Meyer has intensively studied the methods of Robert Lee Camp and Iain McLaren-Owens, two of the foremost authorities on this metaphysical system, and has synthesized both of their approaches in order to come up with a method of understanding relationships that almost anyone can easily understand and practice. He offers a step-by-step approach to the basic system, as well as detailed methods, step-by-step instructions, and worksheets that can be printed out and used for personal practice.
