The Rebbe talks about the special power that dancing and clapping have to make us happy and mitigate the negative things affecting us (Likutey Moharan I, 169). It is customary in every Breslov synagogue to dance each day after the morning and evening prayers. Many Breslover Chassidim dance after learning together, while some even dance daily by themselves. It’s a surefire way to arouse a feeling of real joy and happiness.
Reb Noson once said to Reb Moshe Breslover, “I will give you a way to repent. Dance every day!” (Aveneha Barzel, p. 62).
