Numerology is the study of numbers, and the occult manner in which they reflect certain aptitudes and character tendencies, as an integral part of the cosmic plan. Each letter has a numeric value that provides a related cosmic vibration. The sum of the numbers in your birth date and the sum of value derived from the letters in your name provide an interrelation of vibrations. These numbers show a great deal about your character, your purpose in life, what motivates you, and where your talents may lie.
There are eleven numbers used in constructing Numerology charts. These numbers are 1, 2, 3, 4, 5, 6, 7, 8, 9, 11, and 22. Larger numbers that occur from adding the numbers in your complete birth date or from the values assigned to each name, are reduced until you achieve one of the core numbers. Merely add the components of the larger number together (repeatedly, if necessary) until a single digit (or the "master" numbers 11 or 22) results.
