Sketch illustrating the unified scheme of AGN accretion combining the dusty torus, BLR and accretion disc. Radiation from the accretion disc ionizes and destroys the dusty clouds of the torus and makes them radiate in broad emission lines. The material from the torus and BLR finally precipitates into the disc. A couple of BLR clouds are shown schematically with one side highlighted to indicate the photoionization of the illuminated side of the cloud.
