The people who come to Joao are mostly Brazilian, often poor and unable to afford regular medical care, but sometimes include upper echelon military and political figures, and frequently include people whose doctors have told them there was no cure for what ails them. Most of the people who see him are prescribed herbal remedies made of various medicinal plants from the rich Amazon jungles. Some people are told to have  "operations." These operations are spiritual, in the sense that the "entities" of Casa de dom Inacio work on them invisibly in the "operating room." Of those who are told to have operations, a few elect to have  "visible operations."

I was able to witness dozens of these "visible operations" over the six weeks I spent at Casa de dom Inacio, and experienced my own "invisible operations."  One of these invisible operations (with no physical hands touching me) removed a cyst that had been on my chest for several years in addition to removing some spiritual and psychological energies that had troubled me for decades. It is difficult to fathom these invisible operations, as they are done by the entities--with no human hand or instruments touching one's body. Nonetheless, they are quite real, and I have interviewed many people who have benefited from them.

I saw one man--an American, who I interviewed after his healing--receive the benefits of an invisible operation. Over the past ten years due to a spinal problem, his ability to walk without a cane had deteriorated, and he also became unable to write due to increasing weakness in his right arm.  Within minutes of leaving the "operating room" where he'd received his invisible surgery, he threw away his cane and, with a radiant look upon his face, began walking and running vigorously about to the delighted applause of all who were present. And that night he was able to write for the first time in years.

Hope that gives you a better idea :)
