The Toldos Aharon Rebbe recently spent a Shabbos with 100 of his yungeleit in Tzfas. When he left the room the group began to sing Meshulam Greenberger’s popular new “Mah Tishtochachi Nafshi” a slow moving song with a complex structure of several parts which has become a choir favorite in the months since its release on Greenberger’s newest album Oscha Avakesh. Upon the Rebbe’s return the young men stopped singing since he does not usually approve of contemporary music. But the Rebbe motioned them to continue. And when the song finished he spoke for an hour expounding on the song’s words taken from Tehillim 42:12 — “Why are you downcast my soul and why are you disquieted? Hope to Hashem for I will yet thank Him for the salvations of my countenance and my G-d.”
