The lowest trees have tops, the ant her gall

The lowest trees have tops, the ant her gall,
The fly her spleen, the little spark his heat;
And slender hairs cast shadows, though but small,
And bees have stings, although they be not great;
Seas have their source, and so have shallow springs;
And love is love, in beggars and in kings!

Where waters smoothest run, deep are the fords;
The dial stirs, yet none perceives it move;
The firmest faith is in the fewest words;
The turtles cannot sing, and yet they love;
True hearts have eyes and ears, no tongues to speak;
They hear, and see, and sigh, and then they break!
