How due! yet all his good proved ill in me,
And wrought but malice; lifted up so high
I 'sdain'd subjection, and thought one step higher
Would set me highest, and in a moment quit
The debt immense of endless gratitude
So burdensome still paying, still to owe:
Forgetful what from him I still received,
And understood not that a grateful mind
By owing owes not, but still pays, at once
Indebted and discharged; what burden then?
