How Much Can One Person Love Another

How much can one person love another?
A universe exists in time and space,
Placed within the boundaries of one place,
Pressed into a point far from forever.
Yet love comes to us from some quite other,
Visiting our sorrow with its grace,
Answering our rage with its embrace,
Lending us the wisdom of its wonder.
Even as I say this, you are there,
Nestling in where need undoes the day,
Taking up your small infinity.
Inside my window, you are everywhere,
Nor could I tell how much such love might weigh,
Even were it salient as the sea.
