Book excerpt: Simple Numerology presents the basics of an ancient science that appears arcane but is in fact easily grasped, useful, and fun for the modern seeker. Using a simple, straightforward style accessible to anyone interested in the subject, author Damian Sharp begins with numerology's origins as a metaphysical system practiced by the Sumerians, Chaldeans, Egyptians, Jews (through the mystical practice of Kabbalah), and other ancient peoples. The remarkable scope and psychological depth of number science is discussed, as well as the characteristics of specific numbers, master numbers, and harmony and conflict between numbers. Readers will learn how to calculate their birth number, name number, motivation number, image number, self-expression number, challenge number, and destiny number. The book includes a numerical compatibility chart for assessing love and friendship.
