Mentally, physically and emotionally we are the same.
We each have the potential to good and bad and to be overcome by disturbing emotions such as anger, fear, hatred, suspicion and greed. These emotions can be the cause of many problems.
On the other hand if you cultivate loving kindness, compassion and concern for others, there will be no room for anger, hatred and jealousy.
What I needed most was to love and to be loved, eager to be caught. Happily I wrapped those painful bonds around me; and sure enough, I would be lashed with the red-hot pokers or jealousy, by suspicions and fear, by burst of anger and quarrels.
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.
Love shouldn't be about jealousy or anything like that. It should be about commitment and being able to trust that person. If you can't have that from the get-go, there's a problem.
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.
