When she left Brazil, Lisa says she followed the guidelines she had received from John of God, such as abstaining from sex and alcohol for 40 days. She later had a biopsy and, unfortunately, her tumor was still malignant.

"It's never gone away, meaning I've never been out of the cancer realm," Lisa says. "I was told I was at a fourth-stage diagnosis."

Even though Lisa did not experience a physical healing at the Casa, she says she has no regrets.

"I know that I carried the loss of my mother for years—that sadness, that feeling of being deprived of a mother," she says. "And [being at the Casa] was an uplifting, joyful, peaceful experience. It wasn't uncomfortable. There was an energy about so many people seeking help."
