Any successful activity on site requires good preparation. This is especially so when working with energies where all cases are different and difficult to compare. For example, buildings may be constructed according to the same designs, but do not have the same position, they lie on different plots of land and their orientation is different, the walls are made of different materials, concrete roof structures are used and the like, so that every building has a different energy potential. The therapist must take into account the material of which the floor is made, and the thermal and hydro insulation, because there is a large difference in the functioning of energies between artificial and natural materials. One must obtain all these construction data from the patient and take them into account when systematically treating and analysing the area in question.
