This sefer contains a collection of Rav Shlomo Wolbe Z'tl's Lectures on Chodesh Elul and Yom Hadin  in Yeshives Bair Yakov. Rav Shlomo Wolba was Born in Berlin shortly before the outbreak of the World War One, Rav Wolbe's early education was in Berlin, in the Yeshiva of Frankfurt, and then in Rav Botchko's yeshiva in Montreux, Switzerland. In the 1930s, he decided to learn in Eastern Europe, spending several years in Mir, Poland, where he became a close talmid of the Mashgiach, Rav Yerucham Levovitz, and, after Rav Yerucham's passing, of Rav Chatzkal Levenstein. Throughout Rav Wolbe's life, he viewed himself as a talmid muvhak, of Rav Yerucham, and as a transmitter of the mussar tradition that traces back to Rav Yisroel Salanter.
