Really happy to see the new book joining the impressive display of Piaseczno Hasidic works at my favorite local Jewish bookstore! Here I am (out of uniform, sorry) with Rabbi Ari Silverstein at Judaica Plus in Cedarhurst.

Just behind classics by Elie Wiesel, Viktor Frankl, and Simon Wiesenthal! Really proud that people are finding this book meaningful. Thank you! Bit.ly\aishkodesh
