Once there was a great assembly of wise men in Rutzfort, Hungary. The greatest men of the country, heavenly saints, were gathered. At their head was the holy Rav Moshe Dovid Teitelbaum AV Bais Din of Madiar-Lapush Zibanbargen grandson of the Yitav Lev. He petioned the Belzer Rebbe Rav Yissacher Dov: The people of Israel are in dire straits throught almost the entire world...There is no remedy save an awakening to repentance.
He petioned the Rebbe of Belz in this way for almost an hour. The Rebbe opened his holy mouth and answered briefly and to the point: "O Rav of Lapush have you finished your petition? When Mashiach arrives the jews will repent. In the meantime it is of utmost importance that we love one another. One must love even the lowliest Jew as himself. One must engender unity - achdus and keep far away from anything that causes disunity. The salvation of Israel during times of trouble rests on this."
