This expression is often attributed to the teachings of the Lubavitcher Rebbe. It emphasizes that every farbrengen (a Chassidic gathering, usually involving inspirational talks, singing, and communal bonding) should lead to a practical outcome. The word "בכן" (b'chein) means "therefore," signifying that after the inspiration and spiritual elevation experienced during the farbrengen, there should be a concrete resolution or action that follows.
The idea is that inspiration alone is not enough; it must translate into tangible change or improvement in one's behavior or spiritual practice.
