In what appears on the surface to be a children's story, Gareth Knight, using Tarot imagery, conducts a guided visualisation through the Tree of Life. Richard and Rebecca meet the Joker of their granny's pack of cards, and guided by his dog, embark on an adventure through the InnerWorlds in search of their True Names. To those attuned to its deeper symbolism, the story forms an imaginative journey along the serpentine path of the Tree of Life, conducted via the Tarot archetypes, which when read with openness and imagination may serve as a powerful key to intuitive understanding of the Western Mystery Tradition.
