Kfar Chabad is the Chabad village in Eretz Yisrael, founded with the Previous Rebbe's blessing and guidance (see also Zalman Shazar), and organized as a moshav. The Vaad is its elected village committee, responsible for its communal, agricultural and municipal affairs. The Rebbe's letters to the Vaad in the Igros Kodesh span about fifteen years (roughly 5714–5730, 1954–1970).
Planning and growth. The Rebbe was closely involved in the village's development: integrating all available land for housing and agriculture (IK 4105), planning land use with expert advice (IK 7069), putting essential public needs before expanding housing (IK 8283), prompt and transparent allocation of housing and farmland (IK 8146, 8157), a structured loan plan to help residents (IK 6978), and practical steps such as opening a post office (IK 6725). Again and again he warned against delays in essential projects (IK 3498, 4546, 4598) and called for proactive leadership that anticipates needs (IK 5509, 5411).
Community over individual. He urged organized communal planning over individual action (IK 5688), putting communal needs before personal interests (IK 5943), stability rather than frequent upheavals (IK 7393), unity among committees and openness to constructive criticism (IK 7379), and responsible handling of communal funds (IK 8149). Kfar Chabad must safeguard its spiritual independence from outside influence (IK 6085).
Unity and peace. The letters repeatedly stress that unity and peace among all residents are the vessel for G-d's blessing and protection (IK 5783, 8642, 9949). When violence occurred, the Rebbe wrote that it contradicts both Torah law and chassidic values (IK 8128).
Shemitah and agriculture. He asked the Vaad to prepare for Shemitah and to act immediately to support farmers facing hardship because of it (IK 5411, 6501).
A spiritual center. Many letters are the Rebbe's messages to the village's farbrengens for Yud-Tes Kislev and Yud-Beis Tammuz (IK 6607, 7361, 7508, 8268), urging it to grow both physically and spiritually, with Torah, Chassidus, kindness and prayer (IK 8717, 9616, 10458, 10814). Involvement in the work of Kfar Chabad, he wrote, connects one deeply with the Nasi (IK 6651).
