In 1983, Nettles had an eye surgically removed as a result of cancer diagnosed several years earlier. While she lived for two more years, dying in 1985, Applewhite told their followers that she had "traveled to the Next Level" because she had "too much energy to remain on Earth", abandoning her body to make the journey. His attempt to explain her death in the terms of the group's doctrine was successful, preventing the departure of all but one member. However, Applewhite became very depressed. He claimed that Nettles still communicated with him, but he suffered from a crisis of faith. His students supported him during this time, greatly encouraging him. He then organized a ceremony in which he symbolically married his followers; Lalich views this as an attempt to ensure unity. Applewhite told his followers that he had been left behind by Nettles because he still had more to learn—he felt that she occupied "a higher spiritual role" than he did. He began identifying her as "the Father" and often referred to her with male pronouns.
