Shabbat Teshuvah

In general, Shabbat was given to Israel as a time for Torah study and prayer, and one should always take care not to pass the time idly or in inappropriate conversation. This is especially true on Shabbat Shuvah during which one should be careful to concentrate entirely on Torah, prayer, and reflection on repentance, thereby attaining forgiveness for whatever unfitting behavior may have marred other Sabbaths.

The Teshuvah done on this Shabbat is more elevated than the teshuvah done on all the other Shabbatot of the year. Thus, it elevates all of them.
