Day of Hilula
Hai Gaon
כ׳ בניסן
Babylon
In Jewish tradition, the day of a tzadik's passing — the 'Hilula' — is not a day of mourning, but a day of spiritual elevation and awakening. According to the teachings of Kabbalah, on this day the soul of the tzadik ascends to a higher realm, and their light and merits shine upon the world. Many Jews mark the day through Torah study, reciting Tehillim, lighting a memorial candle, and good deeds for the elevation of the soul — to connect with the tzadik's path and qualities.
His Life and Legacy
Hai Gaon, the son of Sherira Gaon, was the last Gaon of Pumbedita. He was among the greatest halakhic authorities, and his responsa became renowned throughout the Jewish Diaspora.
"We do not claim knowledge in a matter for which there is no definitive halakhic ruling."
