Author Brian Keats says: "There are two parts to this biodynamic guide. The outside of the publication defines the biodynamic meaning and sets it in its agricultural and scientific contexts. The inside, with its three rotating perpetual wheels, explains connections to Sun rhythms, the eight biodynamic preparations and Moon phases. Understanding and working with these cosmic relationships assists the life of our agricultural activities. Very colorful and well liked by all who see it!
