States are fleeting, temporary aspects of phenomena found in all four quadrants. In the Upper Left, for example, there are the three great natural states of waking, dreaming, and deep dreamless sleep; meditative states; and peak experiences (all of which can be accessed by virtually any level of development). Other examples of states include brain states in the Upper Right; cultural states (e.g., mass hysteria) in the Lower Left; and weather states in the Lower Right.
