The Fibonacci spiral diagram is seen most clearly in the bracts of a pine cone, the growth of a sunflower, the unfurling of a fern frond, in shells such as ammonite, and in the proportions of what is considered by many to be a beautiful face.
The Fibonacci Spiral is also known as the Golden Mean, the Golden Ratio and The Divine Proportion. It is used by many architects and artists throughout the centuries, including ancient Greece (for its temples) and such artists as Leonardo da Vinci (famously in his Last Supper underlying design). The Fibonacci spiral: an approximation of the golden spiral created by drawing circular arcs connecting the opposite corners of squares in the Fibonacci tiling; this one uses squares of sizes 1, 1, 2, 3, 5, 8, 13, 21, and 34.
Placing an object, drink or food either on the Fibonacci coaster or in the Fibonacci mug helps to resonantly, autonomically tune that object to this natural pattern; when you focus on this identification, and then use the object, the natural balancing of your energy field is strengthened. You can frame or place the Fibonacci card in a place where you can focus on the diagram, for help in soothing and balancing your own energy, or that of the room in which it is placed.
