Seeing is an activity; it is not passive. 

There are layers of images—that’s what I meant, very simply. There is thickness. Vision is multidimensional and simultaneous. (...) 
An event in perceiving. It is a speed that you catch. Images are not still. They are moving things. They come, they go, they disappear, they approach, they recede, and they are not even visual—ultimately they are pure feeling. They’re like something that calls you through a fog or a cloud.
