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.]
There is a soul-jealousy that can be as frantic as any body-jealousy.
Men of profound sadness betray themselves when they are happy: they have a mode of seizing upon happiness as though they would choke and strangle it, out of jealousy—ah, they know only too well that it will flee from them!
He whom the flame of jealousy encompasseth, turneth at last, like the scorpion, the poisoned sting against himself.
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.
