I've often wondered about this too. I doubt that anyone has sued, because of the expense of hiring expert witnesses. There can't be many professional eye men who've ever come across people who regularly do the so called 3rd eye meditation, & even fewer who would think to ask the right questions of a patient in order to discover the reasons for any deterioration .

I'm convinced though, that there must be people who've inadvertently damaged themselves whilst seeking to merge with the golden doughnut.
