The Tzaddikim and the Sefiros

In the introduction to Ben Baisi, his son Rav Monish writes that he heard his father say that each of the tzaddikim of the lineage corresponds to a sefirah. Rav Tzvi of Zidatshuv corresponds to chessed; Rav Moshe of Samvor to gevurah; Rav Yehudah Tzvi of Rozla to tiferes; Rav Yitzchok Isaac of Komarno, his father, to netzach; and Rav Yitzchok Isaac of Zidatshuv to hod. Rav Eliezer Tzvi himself corresponded to yesod and malchus. Therefore he passed away on the 39th day of the Omer, which corresponds to netzach of yesod: netzach was his father, and he was yesod.
