And how they kist each other's tremulous eyes. - John Keats

Softly the breezes from the forest came,
Softly they blew aside the taper's flame;
Clear was the song from Philomel's far bower;
Grateful the incense from the lime-tree flower;
Mysterious, wild, the far-heard trumpet's tone;
Lovely the moon in ether, all alone:
Sweet too, the converse of these happy mortals,
As that of busy spirits when the portals
Are closing in the west; or that soft humming
We hear around when Hesperus is coming.
Sweet be their sleep.

They will explain themselves — as all poems should do without any comment.

He ne'er is crown'd
With immortality, who fears to follow Where airy voices lead.
