Gematria (from Greek geometria by way of Hebrew) is a form of reckoning similar to numerology that derives from Kabbalah practice; it involves seeking out patterns in numbers and texts, and derives originally from the practice of writing numbers using Hebrew letters and adding up or otherwise massaging the letter values of various significant words. The practice is considered rather looney by mainstream Judaism (or at least not considered a legitimate form of Torah exegesis), but is taken very seriously by mystics, both kabbalist and otherwise.
