In the winter of 1942, the sixth Lubavitcher Rebbe, Rabbi Yosef Y. Schneersohn, gave his son-in-law, the future Rebbe, the task of compiling an anthology of Chasidic aphorisms and customs arranged according to the days of the year. The calendar was entitled Hayom Yom...In describing this work, Rabbi Yosef Yitzchak wrote:..."A book that is small in format"..."but bursting with pearls and diamonds of choicest quality"..."A splendid palace of Chasidism." True to these words, Hayom Yom... has become a beloved, classic work and a source of daily spiritual sustenance and inspiration.
