The jealousy that arises from another's achievement is overcome by developing an awareness of and admiration for one's own and other's achievement.
A jealous person is doubly unhappy-over what he has, which is judged inferior, and over which he has not, which is judged superior. Such a person is doubly removed from knowing the true blessing of creation.
Jealousy is in some measure just and reasonable, since it merely aims at keeping something that belongs to us or we think belongsto us, whereas envy is a frenzy that cannot bear anything that belongs to others.
Jealousy springs more from love of self than from love of another.
The sure mark of one born with noble qualities is being born without envy.
Jealousy lives upon doubts. It becomes madness or ceases entirely as soon as we pass from doubt to certainty.
Jealousy is bred in doubts. When those doubts change into certainties, then the passion either ceases or turns absolute madness.
Jealousy is the greatest of all evils, and the one that arouses the least pity in the person who causes it.
The truest mark of being born with great qualities is to be born without envy.
What makes the pain we feel from shame and jealousy so cutting is that vanity can give us no assistance in bearing them.
