lainiej, Im afraid something Octavius said is highly relevant, and I am supporting him in it and trying to save you wasting your money: "A qualified practitioner would tell you exactly where to put it. Another qualified practitioner would say exactly the opposite. How would you know?"
Your Buddha's granite, you say, and i take that 'for granite'. Wind and rain will give it an authentic patina without actually defacing it. That's what the wind and water of 'feng shui' should do in a garden, is all.
Youre not (gasp) offended, are you?
