There are many Niggunei Hisvaadus (farbrengen niggunim).
Farbrengen is a time of deep reflection. It calls for a revival of one’s commitment, connection and refinement. The niggunim sung there are what make that happen. They open the doorway to the heart’s inspiration and the soul’s passion. Generally, they are serious and heartfelt; they dig into the recesses of the heart and uncover the depth of the soul and its longing for G-dliness.
