Mark Golding "Enneagram"
Oh man, if I had known about Mark Golding's work, you can bet I would've tried to have included some of it in my Sigils & Signs show. He creates meticulous mandalas and colorful diagrams of his own spiritual experiences. In some cases, as with his Practical Magic series, they are intended to be used as tools of visualization and manifestation. Plus, they look awesome. You can see more at his website, Healing Magic, or on his Facebook page.
