Bagua A bagua is a tool used to map an area to facilitate the flow of chi. A traditional bagua is octagonal, each of the eight segments associated with a feeling and therefore an element, shape and colour. The traditional bagua is aligned to the compass before an area is mapped out.The western bagua uses a nine panelled grid, with each panel associated with a feeling and therefore an element, shape and colour.The base of the grid is aligned against the wall of a room which has the main entrance contained within it. The room can then be divided into nine sections, each corresponding to a bagua panel. Objects that possess qualities of an element can then be rearranged to promote the flow of chi in a certain area of a room.
