How long has it been, since I measured time in songs, and distance in cigarettes?

I know now less than I did, and then I knew worse than nothing.

If the light in me is darkness, how great is that darkness.

What must I do? Tell me.

To know nothing. To see in the darkness.

Teach me. I can't see. Teach me how to listen.

 

How long has it been, since I was able to see in my own eyes?
