Abstract
In this paper I present evidence suggesting that the absence or presence of Hidden Broad Line Regions (HBLRs) in Seyfert 2 galaxies is regulated by the rate at which matter accretes onto a central supermassive black hole, in units of Eddington. I discuss the above findings in the context of a model proposed by Nicastro (2000), in which the existence of the BLRs is regulated by the disk accretion rate. For low enough accretion rates, the disk is stable, and the BLRs do not form.
