Variations in light and dark create planar space. Value gradations evoke gradual movements across a plane or around a sphere. Even,flowing tones create a gentle curve, while abrupt changes in value produce sharp or abrupt angles in space. Depict in your own way the pattern of dark and light values you see within the rectangle. After the exercise, the slide is focused so that image is clear.
All compositions have an abstract foundation of lines, values, and shapes.
Mathematically a circle is defined to be the set of all points in a plane equidistant from a given point called the center of the circle.

Mandalas are found everywhere and have powerful symbolism across all cultures All circles have a center. This is principle of the center.
