The Rebbe's guidance on the chassidic farbrengen — its purpose, how to run it, and what should come out of it:
Its power. Farbrengens have great power to inspire others toward Judaism and leave a lasting impression through the year (IK 1147, 5143, 8220), and they foster unconditional love among Jews (IK 4135). Melaveh Malkah gatherings have a similar effect (IK 5166). Participate actively and seize every opportunity to join a farbrengen (IK 5122, 7138, 5076), balancing being influenced by others with influencing them (IK 2569).
Reaching beyond one's circle. Farbrengens should be welcoming and accessible, drawing in new faces and those distant from Chassidus (IK 3280, 3866, 3907, 5987, 4990). Both new and traditional forms of farbrengen should be maintained (IK 4440); both a shul and a private home have their advantages as a venue (IK 3148). Farbrengens also influence youth indirectly (IK 3927), and should be complemented by a regular Chassidus shiur (IK 4171).
Conduct. Farbrengens must be conducted with order and purpose, with proper speech and conduct befitting those representing Chassidus (IK 7408, 6968, 6359). Drinking mashkeh was once widespread, but today much greater restraint is needed; mashkeh must serve the farbrengen's purpose, not the other way around (IK 1927, 7408). Fill farbrengens with vitality, joy and song (IK 7929, 10321).
From inspiration to action. The inspiration of a farbrengen must be turned into practical action and ongoing growth (IK 3474, 4892, 4983, 7207). Follow up afterward: share resolutions, maintain contact with participants, and report on what was done (IK 1325, 5522, 3298). Prepare thoroughly for major farbrengens such as Yud-Tes Kislev (IK 5885, 5033).
