The Na’vi live in harmony with nature which is true Feng Shui! They talk about their spiritual connection “Eywa” which I interpreted to be what we call “Qi” in Feng Shui. This unseen life energy that exists is what keeps them all connected to and be a part of nature. The Na’vi pays their respect to all living things including plants and animals and they do not abuse what nature has provided. We must re-learn those ways. In taiji we learn that life is a cycle and I believe we are ready to embrace nature and return to our roots.
A good way to start would be on an individual level by simply recycling and re-evaluating our real needs as opposed to just wants. Small steps in the right direction is a good beginning.
