There is a thought
I have just had
Which I don’t care to pass to
Anyone at all at this time.
I have even forgotten it now,
But kept only the pleasures
Of my property
And of my controlled mental slippage.

My eyes have blinked again
And I have just realized
This upright world
I have been in.
My eyelids wipe
My eyes hundreds of times
Reseting and renovating
The scenery.
END

Sister, without you,
The universe would
Have such a hole through it,
Where infinity has been shot.
This cannot be, though.
There will always be room
For you—all of us are
Holding the way open.
END
