Why the Focused Rest of Shabbat is Important

Why the Focused Rest of Shabbat is Important :

Rest and action are two poles of existence. Whatever one is doing, one is either resting or exerting oneself. Exertion complements rest and rest complements exertion as day complements night and night complements day. The reader knows from universal experience, that exercise leads to a deeper sleep and that without resting, one cannot have the energy to act. Therefore, the question of primary importance, as with all pairs of opposites, is the question of balance.
