The Shabbat after Simchat Torah is called Shabbat Bereshit, the "Shabbat of the beginning," that is, the first Shabbat of the annual cycle of Torah reading, where the first section of the Torah, called Bereshit, is read.
The weekly Torah reading defines the Jewish week, serving as a guide and point of reference for the week's events, actions, and decisions. Rabbi Shneur Zalman of Liadi called this idea "living with the times.".
So, the theme and tone of this week is one of beginnings and renewal, as we enter a new life cycle with Torah. The Chabad Rebbeim used to say, "Just as one stands on Shabbat Bereshit, so goes the whole year.""
