Can you see it rising like mist off the pavement?
Can you see it coalescing gray on fabric walls?
Can you see a wave cresting in the air, a following sea?
If you look at someone's head, can you see their mind?
Can you see thoughts form and spring, dissolve, orbit, spiral out, trail behind?
What does attention look like?
Can you see music? --not heads and stems and staves, but notes with evolving shape and color
and motion.
Can you close your eyes and see the shape of an orchestra, and name instruments by genus and species?
Can you see the form of a sonata as it lives?
Can you make out the composer's signature in the corner?
When you look at rain, do you see the river and the sea?
When you look at mountains, do you see sediment? Do you see mountains waiting underground?
If you can see these things, then see one thing more:
The inside of your eye.
