In other words if you carry out certain things its already been done in your heart. You rob a bank in your heart before you step foot in the door. Thoughts are a gateway like movie previews to your actions...good or bad. You can dwell on the wrong thing for too long before it goes from your head to your heart. Its nothing wrong with wanting to be married or gleaning things from others relationships. I guess you should've asked her why she can't stay in a relationship at all. Those are details missing in what you've said to us. Does she want to be married, or does she want to be married to her friends husbands? That's really the question of envy
Very interesting posts. I didn't want to turn this thread about my friend and I've already given her some advice on her situation but am more curious about the concept of sin since she mentioned that she felt she was guilty of the sin of envy. My advice to her was that it was just human to feel envious and nothing to worry about as long as she didn't do something to hurt anyone over that feeling.
When I am talking about distractions that cause mental suffering in a Buddhist context isn't about sin or about morality but about thoughts that take ultimately are futile. For example if I obsess about money and do anything to obtain it because I think that will make me happy I might find that instead I feel very stressed about how I can make more money. The pursuit of money instead of making me happy makes me more unhappy. One of the paths of the Eightfold Path is Right Thought that teaches that we should think about things that go beyond just momentary gratification or momentary suffering. Right or wrong thought though doesn't constitute a sin as a violation of sanctity or something that makes you feel guilty. In the sense that guilt leads to suffering then it isn't right thought either.
