" What cannot help but astound us is that Hasidim remained Hasidim inside the ghetto walls, inside the death camps. In the shadow of the executioner, they celebrated life. Startled Germans whispered to each other of Jews dancing in the cattle cars rolling toward Birkenau: Hasidim ushering in Simhat Torah. And there were those who in Block 57 at Auschwitz tried to make me join in their fervent singing. Were these miracles? Some of those that failed? Perhaps.
Yet there is something else. There is the spark lit in the Carpathian Mountains which has refused to go out. On the contrary, it rekindles our own wavering flame. Consolidated in Jerusalem, Hasidism reappears in the Diaspora everywhere. It would be difficult to imagine a more curious phenomenon: with almost the totality of its followers lost in the Holocaust, Hasidism today is throbbing with newly found vigor. At the Lubavitcher court in Brooklyn, you can see hundreds of youths from every corner of the land. I met Hasidim in Leningrad, Kiev and Moscow, and I was deeply moved by their hidden faith. "
