the clod and the pebble

"Love seeketh not itself to please,
Nor for itself hath any care,
But for another gives its ease,
And builds a heaven in hell's despair."

So sung a little Clod of Clay,
Trodden with the cattle's feet,
But a Pebble of the brook
Warbled out these metres meet:

"Love seeketh only Self to please,
To bind another to its delight,
Joys in another's loss of ease,
And builds a hell in heaven's despite."
