I have had the pleasure of reading the first edition over 20 years ago...This is a masterpiece delivered by a master numerologist. Simple and inviting, this book will help you to answer all of your questions and help you to understand your relationships to family, friends, loved ones and coworkers. Mr. Strayhorn shows you how to work with the numbers from the ancient Chaldean to the Pythagorean method. His unique and original method of "birth key numbers" will tell you which child looks or takes after which parent in the family. You'll find yourself walking around reciting the numbers and "reading" their integral meanings as they relate to your everyday life. What a great book !!!!!
