Jealously is always born with love but it does not die with it.
François de La Rochefoucauld

Who surpasses or subdues mankind, must look down on the hate of those below.
Lord Byron

The jealous are possessed by a mad devil and a dull spirit at the same time.
Johann Kaspar Lavater

Jealousy contains more of self-love than of love.
François de La Rochefoucauld

Live on doubts; it becomes madness or stops entirely as soon as we pass from doubt to certainty.
François de La Rochefoucauld

Jealousy is indeed a poor medium to secure love, but it is a secure medium to destroy one’s self-respect. For jealous people, like dope-fiends, stoop to the lowest level and in the end inspire only disgust and loathing. — Emma Goldman

Jealousy is a kind of civil war in the soul, where judgment and imagination are at perpetual jars. This civil dissension in the mind, like that of the body politic, commits great disorders, and lays all waste. Nothing stands safe in its way; Nature, interest, religion, must yield to its fury. It violates contracts, dissolves society, breaks wedlock, betrays friends and neighbours. No body is good, and every one is either doing or designing them a mischief. It has a venom that more or less rankles wherever it bites: And as it reports fancies or facts, so it disturbs its own house as often as other folks. — William Penn

Jealousy is one of the wickedest of all the passions. It is that which has been the most fruitful mother of tragedies, murders, and wars. But reprehensible though it is, jealousy is almost rather to be pitied than blamed–its first victims are those who harbour the feeling. — Arthur Lynch

Love may be blind but jealousy has 20-20 vision

Jealousy is not a barometer by which the depth of love can be read, it merely records the degree of the lover’s insecurity. — Margaret Mead

More men die of jealousy than of cancer. — Joseph P. Kennedy

Comparison is a very foolish attitude, because each person is unique and incomparable. Once this understanding settles in you, jealousy disappears. — Osho
Jealousy would be far less torturous if we understood that love is a passion entirely unrelated to our merits. — Paul Eldridge

Jealousy is never satisfied with anything short of an omniscience that would detect the subtlest fold of the heart. — George Eliot

I’ve spent most of my life walking under that hovering cloud, jealousy, whose acid raindrops blurred my vision and burned holes in my heart. Once I learned to use the umbrella of confidence, the skies cleared up for me and the sunshine called joy became my faithful companion. — Astrid Alauda

Jealousy in romance is like salt in food. A little can enhance the savor, but too much can spoil the pleasure and, under certain circumstances, can be life-threatening. — Maya Angelou
O jealousy! thou magnifier of trifles. — Johann Christoph Friedrich von Schiller

Jealousy is simply and clearly the fear that you do not have value._ Jealousy scans for evidence to prove the point – that others will be preferred and rewarded more than you._ There is only one alternative – self-value._ If you cannot love yourself, you will not believe that you are loved._ You will always think it’s a mistake or luck._ Take your eyes off others and turn the scanner within._ Find the seeds of your jealousy, clear the old voices and experiences._ Put all the energy into building your personal and emotional security._ Then you will be the one others envy, and you can remember the pain and reach out to them. — Jennifer James

Jealousy is that pain which a man feels from the apprehension that he is not equally beloved by the person whom he entirely loves. — Joseph Addison

To jealousy, nothing is more frightful than laughter. — F. Sagan

To cure jealousy is to see it for what it is, a dissatisfaction with self — Joan Didion

Love sees sharply, hatred sees even more sharp, but Jealousy sees the sharpest for it is love and hate at the same time. — Arab Proverb
