Yosef Hatzadik and the Power of Money

A Yom Hillula (Hebrew: יום הילולא, day of festivity) is another word for yahrzeit (the anniversary of a death). However, it differs from a regular yahrzeit in two respects. It refers specifically to the yahrzeit of a great Tzaddik who taught Kabbalah and/or Chassidus, and unlike a regular yahrzeit, which is marked with sadness and even fasting, a Yom Hillula is commemorated specifically through simcha (joy), and festive celebration.
