Gematria (Hebrew: גימטריה) is a form of Jewish mysticism that involves the practice of assigning numerical values to words or phrases based on the letters that comprise them. This practice is rooted in the Hebrew alphabet, where each letter has a corresponding numerical value. Gematria is often used to find hidden meanings or connections between words and concepts, and it plays a significant role in Kabbalah, the esoteric school of Jewish thought. The term "Gematria" is derived from the Greek word "geōmetria" (γεωμετρία), meaning "geometry," reflecting the mathematical nature of the practice. In Arabic, the concept is sometimes referred to as "Isopsephy" (إيزوبسيفي), which also involves the numerical evaluation of letters. Gematria patterns are used to explore the deeper, often mystical, relationships between words and ideas, and they have been employed in various forms of Jewish literature, including the Torah and other religious texts. The practice has also influenced other cultures and traditions, including Gnosticism and certain forms of Christian mysticism.
