Jealousy 

Jealousy is both reasonable and belongs to reasonable men, while envy is base and belongs to the base, for the one makes himself get good things by jealousy, while the other does not allow his neighbour to have them through envy.   
Our envy always lasts longer than the happiness of those we envy. 
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.    
Jealousy lives upon doubts. It becomes madness or ceases entirely as soon as we pass from doubt to certainty.    
To cure jealousy is to see it for what it is, a dissatisfaction with self.
Jealousy can be disinfected with pure respect, trust, love and understanding the foundation and core of a strong and compact relationship. 
Jealousy would be far less torturous if we understood that love is a passion entirely unrelated to our merits. 
The jealous are troublesome to others, but a torment to themselves. 
The worst wounds and the deadliest of them, are not the ones people see on the outside. They're the ones that make us bleed internally.
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. More men die of jealousy than of cancer.   
A competent and self-confident person is incapable of jealousy in anything. Jealousy is invariably a symptom of neurotic insecurity. 
Comparison is a very foolish attitude, because each person is unique and incomparable. Once this understanding settles in you, jealousy disappears.  
Heal your scars into wisdom. 
Jealousy is the jaundice of the soul.
