Numerology is the study of numbers and the relationship between numbers and certain characteristics of an individual's personality. This method of divination is occult in nature and brings together different parts of one's persona and enables one to understand oneself much better. The birth name and birth date are used for all calculations. Each letter in turn is assigned a number. A system called Gematria Numerology is used to determine the numerical value of words. This is the Hebrew system for calculating the numerical equivalence of letters, words and phrases. All words which have the same numerical value, share the same qualities, and reveal still other aspects of the Divine. This differs from other numerology methods in that that numbers are not reduced to a single digit and relationships between words can be determined by similar numerical values. Each letter of the alphabet is attributed to a particular number.
