YES, I AM REALLY INTO THE FENG SHUI / ZEN GADEN IDEA, AND I THINK YOU ARE CHOOSING A RIGHT THEME FOR YOUR GARDEN. MY SUGGESTION WOULD TO GET A BIRD BATH, PAINT IT A CREAMY COLOUR AND PUT WHITE SAND IN IT. SMOOTH THE SAND OUT AND BUY OR MAKE A BAMBOO MINI RAKE. ADD A COUPLE STONES TO YOUR FANCY.
In addition to rearranging your furniture and accessories to change the flow of Chi in your home, you can improve your Feng Shui with the use of a tool called a Ba-Gua. As far back as Confucius, the Chinese linked a moral order of five virtues -- humanity, righteousness, decorum, wisdom, and good faith -- with the natural order, as symbolized by the five elements -- wood, metal, fire, water and earth. Each of these virtues is represented by an element and associated with a life aspiration (such as career or family), a color and a compass direction, as mapped on the Ba-Gua. Use the Ba-Gua to improve different aspects of your life.
I hope this helps, and I leave you with a quote by teh 14th Dali Lama...
