In a very strange way, I found my soul at home with the Baal Shem but driven by the Kotzker. Was it good to live with one's heart  torn between the joy of Mezbizh and the anxiety of Kotzk ? To live both in awe and  consternation, in fervor and horror, with my conscience on mercy and my eyes on Auschwitz, wavering between exaltation and dismay ? Was this  a life a man would chose to live ?I had no choice: my heart was in Mezbizh, my  mind in Kotzk.
