Perserverance with the Ohr HaChaim

Once, when some of his Chassidim came from the kloiz in Haifa, they told the Rebbe, Reb Avrohom Yaakov Friedman that every Shabbos night they study the sefer Ohr HaChaim HaKodosh together. However, when they reached Parshas Vayikra and tried to study his holy words and commentary, they ran into problems – they had difficulty understanding it. They wanted to know if instead they could switch to studying the commentary of the Ramban. The Rebbe’s answer was harsh. “Do you mean to tell me if you study Gemora and reach a difficult point or sugya that you cease learning?!” Under the Rebbe’s guidance the kloiz persisted in its custom and the weekly Shabbos night shiur in Ohr HaChaim continued, as well as in the sefer Toldos Yaakov Yosef.
