So he that's in himself insensible
Of love's sweet influence, misjudges him
Who moves according to love's melody;
And knowing not that all these sighs and tears,
Ejaculations and impatiences,
Are necessary changes of a measure
Which the divine musician plays, may call
The lover crazy, which he would not do,
Did he within his own heart hear the tune
Play'd by the great musician of the world."
