Contemporary forms result from the fusion of Chinese traditions with other cultures. The father of Contemporary Feng Shui is Lin Yun a monk of the black hat sect, native to Taiwan. Lin Yun emigrated to the United States in the 70's where he created feng shui "black hat" with the intention of introducing into Tantric Buddhism American society. This feng shui incorporates elements of "vastu", of Hindu architecture, originating a simple method, of easy assimilation and learning. The house is divided into eight sections each with its meaning. This division is usually called "ba gua". The many variants of this school include intuitive, pranic or symbolic feng shui. Under the designation of Contemporary Feng Shui, disciplines from different parts of the world are also incorporated, namely from the west, which in a direct or indirect way relate to the well-being and the harmony of the dwellings. Examples of this are the geobiology used to determine the energetic lines of the earth, namely the lines of geopathic stress, electromagnetic stress and water lines; sacred architecture studies for example the golden mean ratio to determine the ideal proportions of the interior spaces and used by the masons architects; the space clearing of bali origin and developed by Denise Lynn and Karen Kingston that aims to clean up the trash and the negative and accumulated energies over time. Other contemporary systems such as the eight-way school developed from Japanese ki astrology or the school of eight chi's are useful to harmonize the flow of chi and apply in interior design.
