The Rachmastrivke Rebbe of Yerushalaim shlita related that a group of the Kaliver Rebbe’s chasidim who lived in the city of Nanash, Hungary, once asked him, ‘Who should we accept as our Rebbe after you leave this world?’
He answered. ‘If you find a Rebbe who is able to take the soul of a man who wants to do teshuva and clean it until it is spotless, and then returns it to him, that is the man you should accept as your Rebbe.’
After the Kaliver Rebbe’s petirah, they went in search of a Rebbe. They came to the Ropshitzer Rebbe zy’a and saw a sinful man approach him and list all of his sins. The Rophshitzer Rebbe told him, ‘What did Hashem do wrong to you? Why did you do all of this to Him?’
When the man heard these harsh words, he fainted. When the chasidim from Nanash saw this amazing sight, they smiled. The Ropshitzer said to them, ‘Is it nice to smile when a Jew faints?’
They told him about how their Rebbe had told them to find a Rebbe who cleans neshamos, and they had now found the Rebbe he had described.
May the memory of the tzadik be a blessing for all of Klal Yisroel.
