 In the late 1980s , the group kept a low profile ; few people knew it still existed . In 1988 , they mailed a document that detailed their beliefs to a variety of New Age organizations . The mailing contained information about their history and advised people to read several books , which primarily focused on Christian history and UFOs . With the exception of the 1988 document , Applewhite 's group remained inconspicuous until 1992 , when they recorded a 12 @-@ part video series which was broadcast via satellite . This series echoed many of the teachings of the 1988 update , although it introduced a " universal mind " of which its hearers could partake .
