Reb Chaim Shneur Zalman, the third son of the Tzemach Tzedek, was born a year after the passing of his namesake, the Alter Rebbe. During his youth, when he fell ill, the name Chaim was added. His manner of G-dly service was quite remarkable, with tumult and enthusiasm. Three years after the Tzemach Tzedek's passing he relocated to Liadi and served as a Rebbe to many chassidim. He passed away in 1879.
All through the year after the Tzemach Tzedek's passing, people would not want to join his minyan, for immediately upon the start of his davening, Reb Chaim Shneur Zalman would begin singing and forget where he was, until he 'returned to himself' a long while later.
He was spotted several times striding back and forth during Shmone Esrei, jubilant and dancing, his face aflame. It was said about him, that he had ahava b'tanugim (bliss from closeness to Hashem).
