Space clearing is used in Feng Shui very often. Even though not a traditional Feng Shui application, space clearing is sure becoming a part of contemporary Feng Shui work.
Space clearing means clearing the space on an energy level. It is an ancient art practiced daily in many old cultures – from India and Bali to Peru and Morocco – and there are numerous ways and materials used for space clearing.
The reason behind the need for space clearing is simple: just as on a physical level you see the dust and dirt accumulating in your homeas a result of daily activities, the same happens on an energy levels. You may not see the “dust and dirt” of human emotions, but they do accumulate in any space, so it is best to clear them out regularly.
