Rabbi Chaim Vital, a prominent Safed kabbalist in the 16th–17th centuries, is best known for recording and editing the teachings of Rabbi Isaac Luria, better known as the Arizal, a founder of modern Kabbalah. Chaim Vital’s youngest son, Rabbi Samuel Vital, organized a collection of his father’s writings into eight “gates,” each of which “opens” up a particular topic. The fifth of these is Sha’ar HaMitzvot (Gate of Commandments), which delves into kabbalistic meanings of biblical commandments, in order of their appearance in the Torah.
