Dudaleh
This Niggun is known as the ‘Dudeleh’ of Reb Levi Yitzchok of Berdichev, called this way since 1) a “Dudeleh” means a nice song in Ukrainian and 2) It has the word “Du” (you) many times, in reference to Hashem. The Niggun is based on the idea that everything Hashem does is for the best and Hashem’s presence is everywhere. It was sung by generations of Chabad Chassidim and is mentioned in Toras Sholom (The Rebbe Rashab’s Sichos).
