But the inner faculties of the soul can also perceive beauty that is hidden from the eye of outwardness. The imaginal faculty can perceive beautiful images. The mind can behold the beauty of mathematical forms in the purely mathematical world independent of the material realm. It can also discern harmony, which is inseparable from beauty. The intellect that shines within us can contemplate the beauty of the purely intelligible world and the angelic realms.
