Overview
The origin of this phrase seems to come from the Babylonian Talmud, in tractate Hagigah 15a. This page contains an Aggadic section concerning the heresies of Elisha ben Abuya, an account is given of Elisha’s encounter with the angel Metatron and the subsequent erroneous course of action taken by Metatron. The seeming mistake of Metatron established him as being liable to receive a sentence of 60 Pulsei (pl. of ‘Pulsa’) D'nura: "אפקוהו למיטטרון ומחיוהו שיתין פולסי דנורא" "They took out Metatron and lashed him with 60 pulses of fire."
A pulsa d'nura is also mentioned once in the Zohar (section 3:263c, Raya Mehemna), one of the classic works of Kabbalah (Jewish mysticism). There it is described as a heavenly punishment against a person who does not fulfill their religious obligations. The phrase appears in a small number of other locations in the Talmud and Zohar, but not in the context of a mystical curse.
Some adherents of Kabbalah developed the idea of invoking a curse against a sinner, which they termed pulsa diNura.
