"I thought that as I had failed in the contemplation of true existence, I ought to be careful that I did not lose the eye of my soul; as people may injure their bodily eye by observing and gazing on the sun during an eclipse, unless they take the precaution of looking at the image reflected in the water, or in some similar medium. ...I was afraid that my soul might be blinded altogether if I looked at things with my eyes or tried by the help of my senses to apprehend them. And I thought that I had better had recourse to ideas, and seek in them truth in existence. I dare to say that the simile is not perfect — for I am far from admitting that he who contemplates existence through the medium of ideas, sees them only "through a glass darkly," any more than he who sees them in their working and effects."

...[B]y observing objects with my eyes and trying to comprehend them with each of my other senses I might blind my soul altogether... [like] when [people] watch and study an eclipse of the sun; they really do sometimes injure their eyes, unless they study its reflection in water or some other medium.

For the eyes are the mirror of the soul and ought to remain unscathed if at all possible. Otherwise people will suppose the soul is done for.

... when someone sees a soul disturbed and unable to see something, he won't laugh mindlessly, but he'll take into consideration whether it has come from a brighter life and is dimmed through not having yet become accustomed to the dark or whether it has come from greater ignorance into greater light and is dazzled by the increased brillance.

the liberty of the soul is lost through the windows of the eyes,

3. To prove the truth of the first reason, we take for granted a principle of the philosopher, namely, the more clear and evident divine things are, the more dark and hidden they are to the soul naturally. Thus the more clear the light the more does it blind the eyes of the owl,3 and the stronger the sun’s rays the more it blinds the visual organs; overcoming them, by reason of their weakness, and depriving them of the power of seeing. So the divine light of contemplation, when it beats on the soul, not yet perfectly enlightened, causes spiritual darkness, because it not only surpasses its strength, but because it blinds it and deprives it of its natural perceptions.

People say that eyes are windows to the soul.

The concupiscence of the eyes touches the soul at a higher level than that of the flesh, and is consequently even more subtle and dangerous. Everyone can distinguish sins of the flesh, and most people endeavor to keep themselves from any serious entanglement with them, but it is quite possible to become considerably involved in the concupiscence of the eyes without being in the least aware of the fact.

An eye is meant to see things.
The soul is here for its own joy.

A head has one use: For loving a true love.
Feet: To chase after.

Love is for vanishing into the sky. The mind,
for learning what men have done and tried to do.

Mysteries are not to be solved: The eye goes blind
when it only wants to see why.

A lover is always accused of something.
But when he finds his love, whatever was lost
in the looking comes back completely changed.

A sensible man will remember that the eyes may be confused in two ways - by a change from light to darkness or from darkness to light; and he will recognise that the same thing happens to the soul.

For a moment the feeling crept over me that my work, my vision, is going to destroy me, and for a fleeting moment I let myself take a long, hard look at myself, something I would not otherwise do — out of instinct, on principle, out of self-preservation — look at myself with objective curiosity to see whether my vision has not destroyed me already. I found it comforting to note that I was still breathing.

5) The Eyes Are the Windows to Where the Soul Is Supposed to Be

If the soul, through attentiveness, reduces the blindness caused by the love of this world, it will consider its slightest faults to be very grave and will continually shed tears. ... But if the soul persists in its worldly disposition, even though it commits a murder or some other act deserving severe punishment, it takes little notice; and it is quite unable to discern its other faults, often considering them to be signs of progress, and in its wretchedness it is not ashamed to defend them heatedly.

Why is it that one can look at a lion or a planet or an owl or at someone’s finger as long as one pleases, but looking into the eyes of another person is, if prolonged past a second, a perilous affair?
