If one of two lovers is loyal, and the other jealous and false, how may their friendship last, for Love is slain! But sweetly and discreetly love passes from person to person, from heart to heart, or it is nothing worth. For what the lover would, that would the beloved; what she would ask of him that should he go before to grant. Without accord such as this, love is but a bond and a constraint. For above all things Love means sweetness, and truth, and measure.

Se l'uns des amans est loiax,
E li autre est jalox è faus,
Si est amors entr'ex fausée,
Ne puet avoir lunge durée.
Amors n'a soing de compagnun,
Boin amors n'est se de Dex nun,
De cors en cors, de cuer en cuer,
Autrement n'est prex à nul fuer.
Tulles qui parla d'amistié,
Dist assés bien en son ditié,
Que vent amis, ce veut l'amie
Dunt est boine la compaignie,
S'ele le veut è il l'otreit.
Dunt la druerie est à dreit,
Puisque li uns l'autre desdit,
N'i a d'amors fors c'un despit;
Assés puet-um amors trover,
Mais sens estuet al' bien garder,
Douçour è francise è mesure.
