Poetry at its best can do you a lot of harm.

I?
I walk alone;
The midnight street
Spins itself from under my feet;
My eyes shut
These dreaming houses all snuff out;
Through a whim of mine
Over gables the moon's celestial onion
Hangs high.

I
Make houses shrink
And trees diminish
By going far; my look's leash
Dangles the puppet-people
Who, unaware how they dwindle,
Laugh, kiss, get drunk,
Nor guess that if I choose to blink
They die.

I
When in good humour,
Give grass its green
Blazon sky blue, and endow the sun
With gold;
Yet, in my wintriest moods, I hold
Absolute power
To boycott color and forbid any flower
To be.

I
Know you appear
Vivid at my side,
Denying you sprang out of my head,
Claiming you feel
Love fiery enough to prove flesh real,
Though it's quite clear
All your beauty, all your wit, is a gift, my dear,
From me.

"Soliloquy of the Solipsist", 1956

I shut my eyes and all the world drops dead;
I lift my eyes and all is born again.

For me, poetry is an evasion of the real job of writing prose.

The blood jet is poetry
There is no stopping it.

I Am Vertical

But I would rather be horizontal.
I am not a tree with my root in the soil
Sucking up minerals and motherly love
So that each March I may gleam into leaf,
Nor am I the beauty of a garden bed
Attracting my share of Ahs and spectacularly painted,
Unknowing I must soon unpetal.
Compared with me, a tree is immortal
And a flower-head not tall, but more startling,
And I want the one's longevity and the other's daring.

Tonight, in the infinitesimal light of the stars,
The trees and flowers have been strewing their cool odors.
I walk among them, but none of them are noticing.
Sometimes I think that when I am sleeping
I must most perfectly resemble them--
Thoughts gone dim.
It is more natural to me, lying down.
Then the sky and I are in open conversation,
And I shall be useful when I lie down finally:
The the trees may touch me for once, and the flowers have time for me.

"I Am Vertical", 28 March 1961
