The Teachings of Rebbe Pinchas of Koretz and His Disciple, Rebbe Raphael of Bershad
“Rebbe Pinchas of Koretz taught that a holy spark falls and burns inside a Ger. It compels him to complete his Geirus and actually does not give him any choice in this matter. Only after his Geirus is the Ger given free choice”.
–Imrei Pinchas HaShalem, Shaar Toras Adam (A, B), cited in “Question & Answer With Yirmeyahu — Burning Within,” at A Simple Jew (C)
