    When spectra of the narrow-line regions (NLR) of Seyfert Galaxies are examined, the emission-line ratios show a remarkable similarity, which is hard to understand with current models. What makes this similarity so remarkable is that it holds even over large distance and kinematical scales. In fact, recent observations show NLR outflows reaching 3000 km s-1 in a typical Seyfert 2, NGC 1068. Here, we put forward a new model of the physical conditions in the NLR, which may explain both the similarity in line emission and these amazing outows: radiation pressure dominated, dusty, photoablating clouds.
