I think Ho'opononopono is truly, madly amazing really. Not so much as technique, because the technique is all but non-existent, which is as it should be, it seems. And I would say that personal dynamics are mostly what's 'going on', at least out there in the ordinary world. So, Ho'oponopono is like purification all around, big time, nothing 'personal' in fact, or rather, nothing inherently self-existent, therefore, everything interdependant.
I love it--and have found it deeply humbling, which for me is a sign of the genuine and true.
