Jose Arguellas, proposed the planets in our universe would come together in a rare alignment on August 15-16 signaling the beginning of a New Age. He claimed in his book, The Mayan Factor, that the 5,125 year-old Mayan calendar predicted a celestial change would be taking place on those dates. Arguellas was an artist, founder of Planet Art Network and the Foundation for the Law of Time, an activist for peace and the planetary transformation of consciousness. He was also a major force in the development of The Whole Earth Festival which evolved in to Earth Day that was adopted by the United Nations in 1970.
Months before the event, organizers had met with county and village officials to explain that convergence attendees would be involved in a variety of activities. For example, private and group meditation, chanting, singing, dancing and crafting would be taking place at various times and locations at the Mound for two days in cosmic harmony, thus the name “The Harmonic Convergence”.
