Feelings change intentions, thus changing actions too. When there are negative feelings like jealousy or hatred towards another person, those feelings naturally create misunderstanding. Even if the other person has a good feeling while doing something, a negative intention is attributed and this naturally changes one's own behaviour or response making it negative too. When there is the slightest bit of negative feeling within us for someone, it naturally creates further negativity from others too. We find everything we come across to be negative, like the one who wears colored glasses sees everything to be of that particular color.
