Chai is a Hebrew word that translates to 'alive' or 'living'. In Jewish culture, it serves as both a linguistic term and a visual symbol. The symbol consists of the Hebrew letters Chet and Yod. It is widely recognized as an amulet worn for protection and good fortune. The concept extends to numerology, where the numerical value of the letters adds up to eighteen. This number holds spiritual weight, often influencing charitable giving and gift amounts.
Where it comes from
The use of Chai as an amulet traces back to eighteenth-century Eastern Europe. As a broader symbol, its roots extend to medieval Spain. Jewish tradition holds that letters have deep significance, with the Talmud stating the world was created from Hebrew letters. In medieval Kabbalah, Chai represents the lowest emanation of God, closest to the physical plane. It is linked to the divine attribute of will or motivation.

Jews often give donations and gifts in multiples of eighteen, a practice known as 'giving chai'. Charities suggest specific amounts like eighteen, thirty-six, or fifty-four dollars. The word also appears in the toast 'L'Chaim', meaning 'to life', during social gatherings involving alcohol.
Tools and materials
The primary tool is the written form of the Hebrew letters Chet and Yod. These letters are cast into metal or other materials to create jewelry. The number eighteen is used as a numerical tool in financial transactions and charitable contributions. The symbol functions similarly to other Jewish protective items like the Star of David or the Hamsa.
