On December 22, Birth 2012 Boston will celebrate what organizers call a planetary shift to a new paradigm. The event, which will take place from 7 to 10 p.m. at Arlington Town Hall, includes sound healing concerts, drumming, dance and arts performances, interactive exhibits and peace meditations.

“Planetary Birth Day 12-22-12 is ‘Day One’ of a shift into the emergent global culture of peace that begins on the December 21 solstice,” says organizer eliSabeth Taylor. “Birth 2012 Boston is a local celebration of this historic event, which links hearts and minds to mark the birth of an awakened, heart-centered, universal humanity.”

The Arlington event includes a brief video introducing Birth 2012 co-founder and humanist Barbara Marx Hubbard, an 82-year-old visionary and leader of the human potential movement for four decades. Taylor says that there will be other local events leading up to December 22, and that individuals, groups and organizations can participate and plan their own celebrations. “People can visit Facebook.com/Birth2012Boston to link up with others for action and to share their innate genius, visions, and joys.”
