“Jealousy comes from another person owning “valuable stuff”.”
This is evny not jealousy. In common parlance the two terms have become interchangeable. Most often people are in fact experiencing the feeling of envy when they say ‘I am jealous'(of him, of her). Technically the two terms are given as (Cambridge):
Envy: To feel displeasure and ill-will at the superiority of another in happiness, success, and the possession of anything desirable”
Jealousy: An apprehension of losing something or someone to another, of losing a loved one to a rival. Typically a third person, a rival, enters the scene and attempts to take away a lover.
Now I do not know what the Pali word ISSA stands for exactly. My feeling is that it is envy that is meant, since that is the ‘mental groundwork’, to coin a phrase ,leading to potential theft or appropriation to oneself of something or someone belonging to another; while jealousy is ‘only’ LACK of generosity taken to the extreme, a total unwillingness to share, and a corresponding resolve to protect at all costs what one does have,EVEN BY FORCE.
The one has to do with extreme greed, the other with extreme selfishness/miserliness. There is more evil implied in the first. One is wanting MORE, the other is wanting to HOLD ONTO desperately.
I thought it relevant to make the distinction clear.
