Meditating?

I'm sitting in a quiet place trying to focus on my breath.  I struggle to keep thoughts of today and thoughts of yesterday away. As the thoughts come, I imagine pressing a delete button and throwing them into a trash can.  

Suddenly I hear a voice coming from my left.  It says, "What am I doing, and where am I going?"  I  think, "Yah, that's what I'd like to know too."

I'm in the ocean . . . very, very deep down.  It's dark.  I can't see anything down here. And the pressure.  I can hardly move, the pressure is so great.  I know that I need to go upward. I feel that it won't be as dark and the pressure won't be as great further up.  And it'll get gradually easier and easier to move as I rise.

I . . . just . . . gotta . . . get . . . there . . .
