From the late 14th century, Middle English armonye, Old French armonie, Latin and Greek harmonia. Meaning: agreement, means of joining, framework, agreement of feeling, concord.
As you know, Feng Shui, literally translated into english, is "wind-water." This is a shorthand, taken from this passage from Zangshu, or Book of Burial, by Guo Pu:
Qi rides the wind and scatters, but is retained when encountering water.The goal of Feng Shui is to create harmonious spaces by enhancing the positive flow of Qi, or Life Force, using Nature's elements. This, in turn, creates harmony in our lives. Remember the law: when your space changes, you change too - so best to pay close attention to the ways in which you, or others, change your space! And, don't forget - harmony is a relationship, not a one-way street. Harmony is not created at the expense of others, or at the expense of the earth.
