Who was the Ari?

Isaac (ben Solomon) Luria Ashkenazi (1534 – July 25, 1572) (Hebrew: יִצְחָק בן שלמה לוּרְיָא אשכנזי commonly known as “Ha’ARI”(meaning “The Lion”), “Ha’ARI Hakadosh” [the holy ARI] or “ARIZaL”the ARI, Of Blessed Memory, was a foremost rabbi and Jewish mystic in the community of Safed in the Galilee region of Ottoman Syria. He is considered the father of contemporary Kabbalah, his teachings being referred to as Lurianic Kabbalah. While his direct literary contribution to the Kabbalistic school of Safed was extremely minute (he wrote only a few poems), his spiritual fame led to their veneration and the acceptance of his authority. The works of his disciples compiled his oral teachings into writing. Every custom of the Ari was scrutinized, and many were accepted, even against the previous practice.
