Book excerpt: These mandalas, Martha Bartfeld writes, are keys that have been planted, and each key will open doors to hidden memories when you are ready to experience them. As you look upon these designs, you will find a message about an issue you are dealing with. Each symbol will suggest a telepathic image -- a reminder of the lesson you have come to earth to learn, of your own inner magic. In addition to inspiring guided art meditations, these original geometric patterns are ideal for a wide range of design applications, from stained glass to tattoos. Kids enjoy coloring them as much as adults do.
