A speckled rock is from the dream of a galloping appaloosa. The herd sings its Ceremony of Grass and their dream-stones fly from their hooves into the spattered sky. A black rock has the bear's soul caught in his last sleep. His song circles the stone, giving the it illusion of fur. All yellow rocks keep the secrets of Owls.
All green rocks are the breath of plants singing in nightly joy.
A red fist-sized rock is the love of a man and a woman as their bodies sing on the grass. A gray stone is naturally mournful. It is a word from the common language of the dead. Someday you will understand.
