Robert Browning - Now!

Out of your whole life give but a moment!
All of your life that has gone before,
All to come after it, -- so you ignore,
So you make perfect the present, condense,
In a rapture of rage, for perfection's endowment,
Thought and feeling and soul and sense,
Merged in a moment which gives me at last
You around me for once, you beneath me, above me --
Me, sure that, despite of time future, time past,
This tick of life-time's one moment you love me!
How long such suspension may linger? Ah, Sweet,
The moment eternal -- just that and no more --
When ecstasy's utmost we clutch at the core,
While cheeks burn, arms open, eyes shut, and lips meet!

Robert Browning
