Pythagorean, Chaldean or Lo-Shu?

Numerology is not a single method. The Pythagorean system assigns numbers to letters in sequence and is widely used today.

The Chaldean system is older and uses a different set of letter values, with its own emphasis on the sound of a name.

The Lo-Shu Grid, rooted in Chinese tradition, arranges the digits of a birth date in a three-by-three grid. Each lens offers something different, which is why a consultation may draw on more than one.
