The Tnuos are a way to help you concentrate before the tefila. Sort of like meditation.
RR44 is a little mistaken in the order of the Rebbes of Viznitz. I am going to list them:
R’ Yaakov Koppel Chossid – the Baal Tefila of the Baal Shem Tov
His son, Menachem Mendel, the Ahavas Sholom was Kossov Rebbe
His son, Chaim, the Toras Chaim took over as Kossov Rebbe
The Toras Chaim had two sons, Boruch Shamson who took over in Kossov and
Menachem Mendel, the Tzemach Tzaddik who was Rav in Viznitz while his father was living, then became the Viznitz Rebbe.
The Tzemach Tzaddik’s son, the Imrei Boruch was Rebbe in Viznitz after his father, but he was niftar after only 8 years.
The Imrei Boruch had two sons, R’ Chaim the Antoniya Rebbe and
R’ Yisroel, the Ahavas Yisroel. was Rebbe in Viznitz and moved to Grossvardein (he kept the name of Viznitz Rebbe)
The Ahavas Yisroel (who was niftar right before the war) had a number of sons:
Damesek Eliezer, started the Viznitz Yeshiva in Tel Aviv
R’ Boruch, the Serret Rebbe, moved to Chaifa
R’ Menachem Mendel, the Vishover Rebbe
R’ Chaim Mayer, the Imrei Chaim of Viznitz. He was Rav in Vilchovitz until his father passed away and then he became Viznitz Rebbe. He moved to Bnai Brak.
The Imrei Chaim had two sons:
R’ Moshe Yehoshua, the Yeshuos Moshe who lived in Bnai Brak. His daughters are married to:
The Skvere Rebbe, R’ Aharon, the Satmar Rebbe, the Belzer Rebbe and R’ Menachem Ernster, the Viznitz Rosh Yeshiva in Bnei Brak.
R’ Mordechai, the Ohr Mordechai, who lived first in Williamsburg and then in Monsey, NY.
The Yeshuos Moshe has two sons:
R’ Yisroel and R” Menachem Mendel, both Viznitz Rebbes in Bnai Brak
The Ohr Mordechai has eight sons, I already listed them in my previous post.
