"What did Dr. Hew Len do to the patients, how did he treat them that the results were so spectacular? He didn’t do anything. Not a thing to them nor with them, except looking at their files. He only tried to heal himself, applying an old, traditional community problem-solving system from Hawaii, called Ho’oponopono, adapted to individuals by his Teacher, the late Hawaiian sage Morrnah Nalamaku Simeona. And what was he doing to himself? In his own words: “I was simply healing the part of me that created them”.
Actually, he used to sit in his office and look at the patients' files. While perusing them, he would feel something, a pain, an empathy. Then he started the healing on himself, taking full responsibility for what was going on with a given patient. That's how those people got better, because their doctor had the strange view that it was himself who needed the healing, not them.
Simply put, Ho’oponopono is based on the knowledge that anything that happens to you or that you perceive, the entire world where you live is your own creation and thus, it is entirely your responsibility.Wikipedia
