Gematria (Hebrew: גימטריה, also spelled gematriya or gimatria) is a form of Jewish mysticism that involves the numerical values of letters in the Hebrew alphabet. In gematria, each letter of the Hebrew alphabet is assigned a numerical value, and words or phrases are analyzed based on these values. This practice is used to find hidden meanings, connections, or insights within texts, particularly in the Hebrew Bible and other Jewish religious texts. The term "gematria" is derived from the Greek word geōmetria, meaning "geometry," reflecting the mathematical nature of the practice. Gematria is a significant part of the Jewish mystical tradition known as Kabbalah. Similar practices exist in other cultures, such as the Greek isopsephy and the Arabic abjad numerology, which also assign numerical values to letters in their respective alphabets.
