Shabbat is the name for the seventh day of the week. The Torah tells us, "Six days you shall work, and the seventh day is Shabbat, for the Lord your God."   Shabbat is at the very center of Jewish consciousness. It is repeated more times than any other mitzvah in the Torah, and it is the only ritual observance which is part of the Ten Commandments.  Shabbat is one of the greatest sources of inspiration, and, paradoxically, Shabbat is often the greatest hurdle to those trying Judaism.
