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.

~Rumi

Then again, the eye goes blind when it doesn't want to see why at all. I'm with him on the feet, though.
