The wholeness of geometry is intensified and brought to its maximum potential by inner light in color.

• Inner light cannot be achieved without geometric wholeness (field of centers) present; color depends on geometry.claim0.878
• All wholeness, not just color, may be considered ultimately as a kind of light, communicating with the transcendent realm where pure unity exists.claim0.842
• The geometry of the physical world has the most profound impact on human inner freedom and sense of life.claim0.837
  Central thesis of the chapter.
• Inner light is directly linked to the field of centers: each color exists as a center and becomes more intense through the intensification by other centers.claim0.828
• Colors create light together like centers cooperating to form a larger being; the interaction intensifies each color as a center.claim0.825
• The student experiment demonstrates that bad geometry prevents beautiful coloring and good geometry makes inner light almost automatic.claim0.825
• Inner light is objectively present in some colored things and absent in others, and can be discerned through direct comparison.claim0.814
• Boundaries and hairlines, by both separating and uniting adjacent colors, intensify the light and form larger wholes.claim0.812
