There are a variety of different types of numerology systems available for study. The Chaldean, the Pythagorean (Western), and the Kabbalah are the most popular numerological systems in use today. Each of these systems calculates numbers differently and offers different interpretation of one's life.
1:- The Kabbalah originated in Hebrew mysticism, and interprets only the meaning of the name. The Kabbalah was developed for the Hebrew alphabet, and therefore has only 22 vibrations ranging from 1 to 400. It was adapted for the Greek alphabet, then further adapted for the Roman alphabet.
2:- Abracadabra is a less frequently used form of numerological interpretation. It is based on the subject's name, and uses a series of triangles to arrive at numerical values that provide information about character and events.
3:- New Kabbalah has also been developed for use with the modern Roman alphabet. It, too, is based on name, and relies on Pythagorean methods to determine time periods. The New Kabbalah is concerned more with events than character.
