Two more items for the list of what love wants, from Wm Blake:

The Clod & 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 Hells despair.

So sang a little Clod of Clay
Trodden with the cattles 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.
