The Heart in Rime Royale

We say the heart is love's true source
That all emotion is its trade
But for these things it's no resource
By what it does our lives are made
We take its work with no wage paid
And treat it ill without remorse
Till its complaint we hear in force

O Heart, we beg thee, stay our friend
Through joy and trial companion be
To us, O Heart, your strength do lend
May we at last our error see
And keep from paying final fee
Your task it is our lives to tend
Do not fall broken in the end
