The sense of colour-seeing’s not from light distinct.
So, too, the sudden rainbow of our mind’s instinct.
From sunlight, and the like, all outer colours rise;
The inward tints that mark our minds, from God’s sunrise.
The light that lights the eye’s the light that’s in the heart.
Eye’s light is but derived from what illumes that part.
The light that lights the heart’s the light that comes of God,
Which lies beyond the reach of sense and reason, clod!
By night we have no light; no colour can we see.
Thus, light we learn by darkness, its converse. Agree!
