I showed her Heights she never saw

I showed her Heights she never saw --
"Would'st Climb," I said?
She said -- "Not so" --
"With me --" I said -- With me?
I showed her Secrets -- Morning's Nest --
The Rope the Nights were put across --
And now -- "Would'st have me for a Guest?"
She could not find her Yes --
And then, I brake my life -- And Lo,
A Light, for her, did solemn glow,
The larger, as her face withdrew --
And could she, further, "No"?
