According to Astrology, numerology is used to determine a person's personality, strengths and talents, obstacles, inner needs, emotional reactions and the manner in which a person deals with others. Numerology studies the symbolism of numbers, examines the patterns in a person's life and provides insights about future events.
Numerology uses a person's date of birth and name to determine his or her traits. According to Astrology, numerology can determine the major frequencies of a person because everything in the universe vibrates at a particular frequency. A numerology chart connects each number to a letter in the alphabet to provide insights about a person's character and personality. All numbers are reduced to single digits, one through nine, except the special master numbers 11 and 22. Numbers are reduced by simple addition; for instance, the number 12 is reduced to the number three by adding the numbers one and two. Each reduced number is then assigned to one of the 26 letters in the English alphabet, so that a numerologist can derive information about the person. Each number also has a positive or negative polarity and a unique association. For instance, the number seven has a positive polarity and is associated with the water element and the cardinal quality, according to ASIACT.
