This seminal work on Chassidus was so revolutionary in its day that it could not find a publisher and had to be printed by an underground press. While its deep yet accessible interpretations of Torah and Tanach cannot fail to impress, it minces no words in its criticism of the rabbinate. The whirlwind conflict between Chassidim and Misnagdim comes to life as Rabbi Wein tracks the dynamic history of this subversive book.
