Rebbe Nachman of Breslov repeatedly emphasized the importance of being happy. “It is a great mitzvah to be happy at all times!” (Likutei Moharan II: 24).
Azamra! – “I will sing!” – is his teaching about the way to happiness by always seeking the good points in ourselves and others (Likutei Moharan I: 282).
