Clearly, The Life You Were Born to Live is my most controversial book -- most readers find it extemely accurate -- a few, for reasons I can't begin to explain, find it personally offensive. Let's deal with the core issue: How can adding up the numbers in one's date of birth (on the Gregorian calendar) to determine your "birth number" possibly give valid, reliable, accurate information about your life purpose, potential, and the core issues of your life? It makes no sense. And I can't explain in any kind of scientific or even logical way how it works. AND it is an amazingly accurate method. All I can do is point to the mystery and mechanics of this universe. I was trained in the basics over a decade ago by an unusual man. I worked with individuals for nine years before teaching the system to therapists and others; finally, I wrote the book.
