Peter London eloquently affirms the transformative power of the Creative Encounter, when the artist honestly and mindfully engages in the act of creating an outward manifestation of inner reality.
The book taught me (or retaught me since I had forgotten) how trustworthy is every thought or impulse employed in the act of creation, and how meaningful is the infusion of sacredness the artist gives to the entire process--the process consisting of its trinity: inner being, outer object, and media intermediaries.
Art is sacred because life is sacred, and each of us speaks from our own particular place in the overall holy picture. Our lives are holy as unique expressions of the universal being, and our art is a particular manifestation or incarnation expressing any portion, large or small, of the infinite range of who we are as cosmic beings.
One cannot be "wrong" when expressing oneself this way. One can be authentic or inauthentic to varying degrees. One can move closer or further away from the heart of oneself. The reflective, honest, and opened process leads further and further in, toward that heart.
This was an excellent book, intended I believe for art teachers primarily, but really for anyone seeking deeper meaning and self-knowledge through art-making.
