Shabbos is a day of ecstasy that has aspects of the afterlife. Every person who observes Shabbos properly will be able to experience an intense spiritual pleasure. With this we receive a taste of the reward of Olam Habbah, the eternal world, the world that is a complete Shabbos.

~ R’ Levi Yitzchak of Berditchev zt”l (1740-1809)
