This wonderful, inspiring melody was a favorite of the fourth Chabad Rebbe, Rabbi Shmuel of Lubavitch, known as the "Maharash." Although he was not the composer, it is known by his name, because he sang it often. It is also called the "Eins-zvei-drai-fier" — one-two-three-four melody. Another name given to it is the Nigun "Ein Sof" (Song of the Infinite).
