Ho'oponopono is the Hawaiian ritual of forgiveness. It proceeds from an understanding of the unity of everything in the world, which is true even though we feel ourselves to be seperate. Because of this unity or oneness, nothing can happen in our world without creating a resonance in the observer. It follows that we can only influence problems in the external world if we heal the corresponding inner resonance. To accomplish this, Ho'oponopono relies on four magic sentences: 'I am sorry. Please forgive me. I love you. Thank you.' In this little book Ulrich Emil Dupree describes Ho'oponopono in a simple way that everyone can immediately make their own.
