How Should You Spend Shabbos?

The day of Shabbos was made so that you should be able to devote time to thinking that Hashem created the world out of nothingness. Of course, the obligation to devote time to this mitzvah applies throughout the week as well, but especially on Shabbos. A person who observes Shabbos but doesn’t think about the fundamental principle of Shabbos is missing the point. — Ohr Avigdor Hakdama
