The purpose of the group, based on the book The Artist's Way by Julia Cameron, is for people to meet and talk about their artistic challenges in any field (painting, writing, music etc.) and encourage each other to break their creative blocks and fulfill themselves in their art. If you find people who are sympathetic, you may want to form your own group, meeting regularly to explore the book and supporting each other in their artistic journeys. I have gone through 2 such clusters and can say that it is a very powerful experience. Why not come to a meeting and see for yourself?
