By observing Shabbat we become God's collaborators in Creation. When we rest on the seventh day and give rest to the world around us, just as God did on that first Shabbat, we increase the tranquility and harmony in the universe. Being mindful of the day and relating to it through concrete actions grounded in mitzvah, we infuse our personal universes with holiness and wholeness.
— Rebbe Nachman of Breslov , 7th Heaven by Moshe Mykoff
