Nettles agreed to perform an astrological reading for Applewhite. They had an almost instantaneous "spiritual" connection; Applewhite decided that Nettles was "to be the sage, he the speaker." They left together on New Year's Day of 1973. Nettles' three youngest children were left to remain with their father, while her oldest daughter, Terrie, then aged 20 and skeptical of her mother's ideas, fended for herself. Nettles and Applewhite established Heaven's Gate together as equals, with Nettles running the group and Applewhite speaking for her. Nettles claimed to have communicated with aliens about the Next Level and told Applewhite to tell their followers. In 1976, Applewhite recognized Nettles as higher up on the level of command than he was.
