Using only a name and date of birth, Anne-Sophie Casper's Numerology teaches how to use the art of numerology for self-understanding. Using an original approach that takes the two sides of the brain into consideration, Numerology incorporates methods of both logic and intuition, and then mixes theory and practice through calculations and tests. What are hereditary, expression, and spiritual numbers? How can one find their simple and master numbers and then use them to determine their key elemental energies? This introductory guide breaks down basic information and background on numerology, but then shares the tools necessary to understand different personalities, worlds, and people in greater detail.
