Man may enlarge or narrow his bed
For the water's play, but the water-head—
How can he multiply or reduce it?
As easy create it, as cause it to cease;
He may profit by it, or abuse it,
But 't is not a thing to bear increase
As power does: be love less or more
In the heart of man, he keeps it shut
Or opes it wide, as he pleases, but
Love's sum remains what it was before.
