An explained version of the HaYom Yom: 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 t 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 inspiritaion.
