Balance is a state of tension that occurs when two opposing forces act upon an object. The brain seeks balance in visual compositions. Balance can be achieved through counterbalancing positive and negative forces. Weight, direction, and tension all influence the visual path that the eyes take when viewing an image or gestalt. The center of a composition is never truly "dead" but rather contains underlying forces and power. Physical and visual centers may differ, with the visual center being where the eyes come to rest. Symmetry generally creates a sense of equilibrium while asymmetry can introduce more visual tension through counterbalancing elements.
