"Spreading Judaism" refers to the effort of sharing and promoting Jewish values, teachings, and practices with others. The goal is to increase awareness, understanding, and observance of Jewish traditions and commandments. This can include activities such as teaching Torah, holding Jewish study classes, distributing Jewish books, and organizing campaigns for mitzvot like laying tefillin or lighting Shabbat candles.

In the Chabad movement, spreading Judaism is a fundamental principle. The belief is that every Jew has a divine spark that can be awakened and strengthened. These activities are intended to bring the light and values of the Torah to everyone, fostering a sense of connection and belonging to Judaism, even among those who may feel distant from it, whether religiously or culturally.
