To be a Jew, according to the Rabbi, means to open one's home to Jews, to open one's home to God, to the knowledge of Judaism, to the fulfillment of the commandments, hence the format of Batei Chabad, or the House of Chabad.
The Chabad movement calls for service to God and the fulfillment of Torah laws with the joy that comes from intellectual understanding of the secrets of Torah. Learning Torah evokes positive emotions. Hence the acronym
Chabad or Lubavitch Hasidism (Chabad-Lubavitch) is at once a philosophical doctrine, a social movement, and a religious organization. Chabad is considered the most dynamic and influential force in the modern Jewish world.
As a Jewish religious philosophy, Chabad reveals the highest levels of Torah wisdom, directing the human mind to understand the Creator, to understand the purpose of the world, and to realize the importance and special mission of each creation. Chabad teaches a person to measure every action and feeling with wisdom, understanding and knowledge.
The name "Lubavitch" comes from the name of the Belarusian village of Lubavichi (now Smolensk Oblast), which was the center of the movement for more than a century. Consonant with the word love, this name best reflects the idea of mutual responsibility and love for fellow human beings inherent in the Chabad teachings.
