Quoting Poetry From The Book” Golden Treasury” by Francis T. Palgrave

Fain would I change that note

To which fond Love hath charm’d me so

Long long to sing by rote,

Fancying that that harm’d me:

Yet when this thought doth come

Love is the perfect sum

Of all delight.

The Passionate Shepherd To His Love/ VIII/Omnia Vincit
