Gematria is an ancient Jewish numerological system that assigns numerical values to letters in the Hebrew alphabet. By calculating the sum of the values of the letters in a word or phrase, practitioners believe they can uncover hidden meanings or connections between different words and concepts. This method is often used in Kabbalah, a mystical interpretation of Jewish texts, to explore deeper spiritual insights. Gematria can also be applied to other languages and alphabets, such as Greek and Latin, allowing for a broader exploration of texts and their meanings across various cultures.
