Rebbe Nachman aimed to fix what he believed was an erroneous trend in Chassidus. Though the Baal Shem Tov intended to bring spirituality to the Jewish masses, Rebbe Nachman felt his disciples had lost sight of that mission by making Chassidus too intellectual and complicated. His own emphasis on simple, heartfelt conversations with God over strict adherence to the siddur made him popular with some and controversial to others. But even with opposition and even without a Rebbe to succeed Rebbe Nachman, Breslov Chassidus has grown exponentially and is now enjoying a revival that brings thousands to Rebbe Nachman's gravesite every Rosh Hashanah.
