You can only be jealous of someone who has something you think you ought to have yourself.
When however small a measure of jealousy is mixed with misunderstanding, there is going to be trouble.
Jealousy knows more than truth does.[Los celos saben más que la verdad.]
Jealousy is never satisfied with anything short of an omniscience that would detect the subtlest fold of the heart.
There is a soul-jealousy that can be as frantic as any body-jealousy.
There is a sort of jealousy which needs very little fire; it is hardly a passion, but a blight bred in the cloudy, damp despondency of uneasy egoism.
One of the tortures of jealousy is, that it can never turn its eyes away from the thing that pains it.
He whom the flame of jealousy encompasseth, turneth at last, like the scorpion, the poisoned sting against himself.[Wen die Flamme der Eifersucht umringt, der wendet zuletzt, gleich dem Scorpione, gegen sich selber den vergifteten Stachel.]
Cruelty has a Human Heart, and Jealousy a Human Face; terror the Human Form Divine, and Secrecy the Human Dress.
But jealous souls will not be answer’d so; They are not ever jealous for the cause, But jealous for they are jealous.
Anger and jealousy can no more bear to lose sight of their objects than love.
