The Sanz-Klausenburger Rebbe performs the rare mitzvah of Shiluach Hakein late at night at the chassidus’ new mesivta in Boro Park, built with special architectural niches to preserve existing fruit trees at the Rebbe’s instruction rather than uproot them. Following the mitzvah, the Rebbe held a l’chaim and offered words of encouragement to the bochurim.
