  • Please Join Me in Spain and Portugal

    Please Join Me in Spain and Portugal

    I’m really thrilled to be cruising the Douro River this summer with Kosher Riverboat Cruises, lecturing on the history of Spanish and Portuguese Jewry (my wife plans to come along, which means I really have to bring my A-game). I just learned that there’s only 18 cabins left, so if you’re interested, please click the……

  • “Should We Tear Down Statues of Khmel’nyts’kyi and Petliura?”

    “Should We Tear Down Statues of Khmel’nyts’kyi and Petliura?”

    Conference presentation at the “The 100th Anniversary of the Ukrainian Revolution and the Proclamation of Ukraine’s Independence,” held at the Ukrainian Institute, New York, Sunday, January 21.  My talk was inspired by a thought-provoking article in the Forward by Avital Chizik-Goldschmidt. A fascinating panel, which included Anna Procyk of CUNY, Serhy Yekelchyk of University of……

  • The Aish Kodesh On Beshalah (January 20, 1940 in the Warsaw Ghetto)

    The Aish Kodesh On Beshalah (January 20, 1940 in the Warsaw Ghetto)

    On Parashat Beshalah (January 20, 1940), a young rebel escaped from the notorious Pawiak Prison, located not far from the Piaseczno Bet Midrash. Andrzej Kott, the 21-year old leader of the military wing of a resistance movement called the Polish People’s Independence Action, was a child of assimilated Jewish parents who had converted to Christianity….…

  • The Aish Kodesh and Rav Shagar (Parashat Bo 5702, January 24, 1942)

    The Aish Kodesh and Rav Shagar (Parashat Bo 5702, January 24, 1942)

    The recent translation of the work of Rabbi Shimon Gershon Rosenberg (Rav Shagar, 1949-2007) promises to elevate his distinctive thought to a broader audience of readers (Faith Shattered and Restored: Judaism in the Postmodern Age), many of whom will resonate with Dr. Yitzchak Mandelbaum’s comment on his discovery of Rav Shagar: “I knew I had……

  • The Deleted Drasha: Aish Kodesh on Parashat Bo 5700 (January 13, 1940)

    The Deleted Drasha: Aish Kodesh on Parashat Bo 5700 (January 13, 1940)

    The Rebbe’s entry for Parashat Bo (January 13, 1940) is unusual. Recorded in the scribe’s careful hand, with minimal annotation, it has two bold diagonal lines drawn through the center of the text, indicating that the Rebbe rejected it altogether. A brief and uncharacteristic first-person comment is appended: “more of what we said I do……

  • Working on Spanish Edition of Kabbalah of Forgiveness!

    Working on Spanish Edition of Kabbalah of Forgiveness!

    Really nice to meet with Jésica Neuah of Editorial Perspectivas to work on the tentative cover and book design of the Spanish edition of The Kabbalah of Forgiveness! Great to work with her and the whole team. G-d willing the book will be released in the summer of this year.

  • Rabbi Shlomo Katz on the Aish Kodesh

    Rabbi Shlomo Katz on the Aish Kodesh

    I had chills listening to Rabbi Shlomo Katz review the Rebbe’s words on this week’s parashah. I am grateful for his kind words of praise for my recent book on the historical context of the Aish Kodesh, but to tell the truth, I hardly recognized my own words from the masterful treatment they received from……

  • The Aish Kodesh On Vaera 5702 (January 1942 in the Warsaw Ghetto)

    The Aish Kodesh On Vaera 5702 (January 1942 in the Warsaw Ghetto)

    Chaim Kaplan recorded the mood in the Warsaw Ghetto in January 1942:  The cold is so intense that my fingers are often too numb to hold a pen. There is no coal for heating and electricity is sporadic or nonexistent. In the oppressive dark and unbearable cold your mind stops functioning. Yet even in such……

  • The Aish Kodesh on Vaera 5700 (Torah from the Warsaw Ghetto, January 1940)

    The Aish Kodesh on Vaera 5700 (Torah from the Warsaw Ghetto, January 1940)

    Five months into the Nazi occupation, the Jews of Warsaw struggled to keep up with the barrage of administrative decrees inflicted upon them by the Germans. When the Rebbe spoke on Parashat Vaera, which fell on January 6, 1940, the worst was still far off. The Nazis had replaced the leadership of the Jewish Council……

  • The Aish Kodesh on Shemot 5702

    The Aish Kodesh on Shemot 5702

    The winter of 5702 brutalized the Jews of the Warsaw ghetto with unforgiving cold. Chaim Kaplan, a school principal whose journal Scroll of Agony survived the war, recounts in his typically blunt prose how the physical privations of January 1942 affected the spiritual life of Ghetto inhabitants: Gone is the spirit of Jewish brotherhood. The……

  • The Piaseczno Rebbe on Vayigash

    The Piaseczno Rebbe on Vayigash

    On December 27, 1941, the Piaseczno Rebbe delivered his last recorded drashah on Parashat Vayigash in the Warsaw Ghetto. The previous month was especially brutal: an especially cold winter, combined with a severe coal shortage, exacerbated the typhus epidemic, and each morning a detail of the chevra kadisha patrolled the streets to collect the bodies……
