According to Osho, jealousy never follows love; it follows possessiveness pretending to be love. When you try to own a person, your ego defends its territory and breeds fear and anger. Real love celebrates the other's happiness and gives freedom; where jealousy appears, love is absent, replaced by control and insecurity.
Jealousy comes when we treat people like our property; real love lets them be free and feels happy when they are happy.
