Did you know?
As an element of astrology and fortune-telling, numerology has long been employed to predict future events. For many early Christians, 3 represented the Trinity, 6 represented earthly perfection, and 7 represented heavenly perfection; and still today, many of us like to group things into sets of 3 or 7, for no particular reason. Numerology has also been used to interpret personality; in particular, numerologists may assign numbers to each letter of a person's name and use the resulting figures, along with the person's date of birth, as a guide to his or her character.
