I am climbing the high mountain. I look above and can't see the top, and I don't even think about looking down, fearing I wouldn't be able to see the bottom. How long have I been climbing? I can't remember. Every step

It is dark. Black. Pitch black. Absolute darkness. I wondered if this is how the universe looked before it existed. I see a black line. Just one black line. Then another one. Then a billion black lines at once. How is it possible to see black lines in absolute darkness?
