[Shih can be translated as] the strategic configuration of power [involving] first, the strategic advantage conveyed by superior position, and second, the power of the forces involved. ('Power' refers to an army's overall capability in all aspects - including endurance, spirit, discipline, equipment, command, and physical condition - rather than strength in numbers alone.) ... Strategic advantage has a pronounced temporal character; therefore, it should not be confined to exploiting the advantages of terrain as usually thought. Strategic advantage is of course in essence a comparative term, not an absolute one, although a vast force will possess great power.
