THE SMILE - william blake

There is a smile of love,
there is a smile of deceit;
and there is a smile of smiles,
in which these two smiles meet.
And there is a frown of hate,
and there is a frown of disdain;
and there is a frown of frowns
which you strive to forget in vain,
For it sticks in the heart's deep core,
and it sticks in the deep backbone.
And no smile that ever was smiled,
but only one smile alone --
That betwixt the cradle and grave
it only once smiled can be,
but when it once is smiled
there's an end to all misery.

INFERNO - dante (excerpt)

Maintain the melancholy souls of those who lived without infamy or praise.
