Pulsa deNura, Pulsa diNura or Pulsa Denoura (Jewish Babylonian Aramaic: פולסא דנורא, romanized: pulsā di-nurā, lit. ‘the lash of fire‘) is a purportedly ancient Kabbalistic ceremony in which the destroying angels are invoked to block heavenly forgiveness of the subject’s sins, allegedly causing all the curses named in the Bible to befall him resulting in his death. It is controversial for having been allegedly invoked against several contemporary political figures, including by Yosef Dayan against Yitzhak Rabin before his assassination by the far-right Jew Yigal Amir.

Its historicity has been questioned. Dr. Dov Schwartz of Bar-Ilan University and the Haredi public figure Moshe Yehuda Blau argued in the Haredi magazine Mishpacha that the ceremony has no basis in traditional Judaism and actually originates in the mid-20th century.
