Wind and water
Feng shui literally means ‘wind water’, and is concerned with the movement of energies within the landscape – not just tangible forces like wind and water, or light and shade, but also more abstract energies such as traffic, or the ebb and flow of social support.
Energy and power
Power creates the possibility of change, and energy is the expression of that power – yet there are so many different types of power and energy at work in any given place, and so many possible interactions between them, that the single term ‘ch’i’ is used in feng shui to describe them all.
Flow and movement
Form School feng shui is particularly concerned with the flows and changes of chi’i, and describes them with a pair of simple but elegant transformation-cycles showing constructive and destructive relationships between ‘elements’ or expressions of energies.
Balance and imbalance
Energies are also described in terms of polarities, such as positive and negative, male and female, dark and light, movement and stillness; ideally, these different forms of yin and yang should balance be in mutual support, but where they fail to so, whether through excess or absence, constructive ch’i is transformed to destructive sha.
