Having that power is what we call free will. If you can make a choice, you are never going to choose anger, jealousy, emotional pain, or suffering. You choose that way of dreaming because you have no choice. If you have a choice, you are always going to be happy, always in love. This is the mastery of love.
Every relationship is between two people and only two people.
You are responsible for your half, and the other person is responsible for his or her half. If you think you are responsible for others, you try to control them. You can never know what the other half thinks or believes. This is the truth, but we try to be responsible for the other half, and this is why most relationship are based on fear and drama. To heal a relationship, each person can use the Four Agreements to end drama in their own lives, and focus on healing their own wounds through using the truth, forgiveness, and love.
