Feng Shui

Feng Shui is an ancient Chinese system of aesthetics believed to use the laws of both Heaven (astronomy) and Earth (geography) to help one improve life by receiving positive qi. Historically, feng shui was widely used to orient buildings – often spiritually significant structures such as tombs, but also dwellings and other structures – in an auspicious manner. Depending on the particular style of feng shui being used, an auspicious site could be determined by reference to local features such as bodies of water, stars, or a compass. Feng shui was suppressed in China during the cultural revolution in the 1960s, but has since seen an increase in popularity, particularly in the United States.
Today, feng shui is practiced not only by the Chinese, but also by Westerners. However, with the passage of time and feng shui's popularization in the West, much of the knowledge behind it has been lost in translation, not paid proper attention to, frowned upon, or scorned.
Robert T. Carroll sums up what feng shui has become in some cases:
"... feng shui has become an aspect of interior decorating in the Western world and alleged masters of feng shui now hire themselves out for hefty sums to tell people such as Donald Trump which way his doors and other things should hang. Feng shui has also become another New Age "energy" scam with arrays of metaphysical products ... offered for sale to help you improve your health, maximize your potential, and guarantee fulfillment of some fortune cookie philosophy."
Others have noted how, when feng shui is not applied properly, or rather, without common sense, it can even harm the environment, such as was the case of people planting "lucky bamboo" in ecosystems that could not handle them.
