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.
Love makes you empty - empty of jealousy, empty of power trips, empty of anger, empty of competitiveness, empty of your ego and all its garbage. But love also makes you full of things which are unknown to you right now; it makes you full of fragrance, full of light, full of joy.
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 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.
Jealousy is comparison. And we have been taught to compare, we have been conditioned to compare, always compare. Somebody else has a better house, somebody else has a more beautiful body, somebody else has more money, somebody else has a more charismatic personality. Compare, go on comparing yourself with everybody else you pass by, and great jealousy will be the outcome; it is the by-product of the conditioning for comparison.
