Course given by Pierre Thirault, founder of the European Institute of Feng Shui; as part of the program of cultural workshops “Nature and Culture” organized in the Cour Petral, an old Trappistine abbey of Perche. The goal is to become familiarized with these two sister disciplines: Feng Shui and Geo-biology. Feng Shui is the art of using Chi (breath) to harmonize the environment, in particular, a house’s environment in accordance to the five elements and eight Chinese trigrams. Geobiology is the measurement and control of pollution of the energies of the earth and of the cosmo-telluric environment with the objective of preserving the maximum energy of human life. Its practice requires great focus.
