Starting in the early 1970s, Sarah had been meeting in a small study group along with Alice Hannah, their husbands (both named Richard) and other close friends who were interested in more advanced spiritual study. Friends invited friends to the groups. Some stayed for a time and many others just passed through. Over the years the group existed, the core of what has become known today as "the Michael Teachings" was revealed. Alice Hannah, "secretary" for the original Michael study group in the early 1970s, kept the group's records and created transcripts of their sessions. The information they brought forth provides the foundation of the body of knowledge, which has now expanded as more teachers are trained and students develop more advanced skills. As advanced students progress in their awareness and needs, new levels of information are being revealed that deepen and broaden the original work.
