He who has lifted the veil sees multiplicity in properties,
not in Essence; hence he knows that changes in properties
cannot touch Essence, which owns a perfection subject to no mutability.
Light merely seems to change as it shines through colored glass, but
not in Essence; hence he knows that changes in properties
cannot touch Essence, which owns a perfection subject to no mutability.
Light merely seems to change as it shines through colored glass, but
light has no color.
Its rays shine through the glass
and only then
do hues and tints appear.
Don't you understand?
Come then into my eyes
and...look!
and you will see
a sun shining
through a thousand bits of glass
beaming to plain sight through each
a ray of color
Why should any difference appear
between this one and that?
All light is one
but colors a thousandfold.
