With great effort and perseverance, while sanctifying and purifying himself and abstaining absolutely from the pleasures of the world, the holy tzadik, Chacham Rabbeinu Yaakov Abuchatzeira zt”l, became so immersed in the revealed and hidden aspects of the Torah, that “no secret was hidden from him.” (Daniel 4-6) With great purity and depth, he studied Kabbalah until he was as familiar with the paths of the hidden Torah as he was with the streets of his hometown, Tafilalet, Morocco. He developed many disciples, both his very close students in his renowned yeshivah, as well as the masses who flocked to hear the word of Hashem, receive blessings and advice, and to have their cases judged before him.
