The Vayechi Yosef of Pupa zy”a (quoted in the introduction to Sefer Vayaged Yaakov) related the following in the name of Rav Yaakov Yichizkiya of Chustz zt”l:
Rav Yaakov Yichizkiya once entered the room of Rav Yissochor Dov of Belz zy”a and gave the Rebbe a kvitel. There also was another chasid in the room who handed the Rebbe a kvitel, upon which was written that his name was “Tzvi Elimelech.”
The Rebbe asked the man, “Who are you named after?” The man answered that he was named after Rav Tzvi Elimelech of Dinov.
The Belzer Rebbe then asked him if he learned his namesake’s sefarim, and the man replied that he learned Sefer Bnei Yissochor.
The Rebbe then said, “I would advise you to learn Sefer Igra D’Kallah because those are the words that he said in front of crowds of Yidden and there is a great power of holiness hidden within them.”
