The story you mentioned refers to the practice of Ho'oponopono, a Hawaiian spiritual and healing technique. Dr. Ihaleakala Hew Len is often associated with this story, which claims that he helped to cure an entire ward of criminally insane patients at the Hawaii State Hospital without directly meeting or treating any of the patients. According to the narrative, Dr. Hew Len achieved this healing by focusing on himself and his own inner healing while reviewing the patients' files and repeating the phrases "I'm sorry, please forgive me, thank you, I love you" as part of the Ho'oponopono process.
The story has gained widespread attention and has been featured in various books and documentaries. However, it's important to note that the story's authenticity and the extent of its impact on the patients have been a subject of debate and skepticism.
Ho'oponopono, in its traditional form, is a Hawaiian practice of reconciliation and forgiveness. It is used to resolve conflicts and restore harmony within families or communities. The version of Ho'oponopono popularized by Dr. Hew Len incorporates a more individualized and self-healing approach.
While there are anecdotal accounts of people experiencing positive effects through Ho'oponopono, scientific evidence supporting the specific claims made in the story about Dr. Hew Len's actions curing an entire ward of patients without meeting them is limited or nonexistent.
In any case, if you are dealing with mental health issues or seeking healing, it's crucial to consult with qualified healthcare professionals or therapists who can provide appropriate care and support. Spiritual practices like Ho'oponopono can be complementary to traditional treatment, but they should not be seen as a replacement for professional medical or mental health care.
