Morrnah Nalamaku Simeona revised Ho'opnpono for the West. It's actually a way of life but she and other kauna's were warned about the West. One of her students is Hew Len (who has recently retired). Morrnah was his spiritual teacher and she had him get a Ph.D. in psychology. He has done wonderous things. Here is a playlist of the only long interview of him that I know of. He prefers to stay out of the public eye. He talks about bringing subconscious data to zero point.
