A very small percentage of people choose a "visible" operation where Faria operates without traditional anesthetic. Instead he says he uses "energized" mineral water and the spiritual energies present, the latter of which are provided by groups of volunteers who meditate in a separate room called the "current room". These practices, such as inserting scissors or forceps deep into a nose and scraping an eye without an anesthetic or antiseptics, have been scrutinised by medical authorities and skeptical investigators such as James Randi, who has called for Faria to stop victimizing people with stunts and trickery.
