The first
Rebbe of Zychlin, Rabbi Shmuel Abba, taught that one needs to not only
repent but repent through the learning of
Jewish holy subjects. Reb Zelig was a relative of the Sabba Kadisha of Strikov, Reb Fishel, going to visit him and taking his young son Shmuel Abba with him. Rabbi Shmuel Abba was known as the
Ilui ("genius") of Luvitch and many scholars praised his depth and understanding. When Rabbi Shmuel Abba was older he learned at the Peshischa yeshiva which was led at that time by Rabbi Simcha Bunim of Peshischa. He considered himself one of Rabbi Simcha Bunim's disciples. Rabbi Shmuel Abba had a small following of Hasidim and lived at his father-in-law's house, but when he moved to Zychlin for monetary reasons he acquired a larger following. Shmuel Abba was known as a
miracle worker. Shmuel Abba spent time in jail because his detractors were upset that he practiced
practical Kabbalah. Ninety-five percent of Zychliner Hasidim perished during
the Holocaust, the last Rebbes dying at the hands of the
Nazis. ==Dynastic line==
