I affected the greatest sanctity of manners, imitating, as far as possible, the Fakys, whose character is the more respected in these countries from their enjoying the reputation of great learning, and of exemplary private conduct. This is the character of the whole body, but it is well known how unworthy many individuals are of it, and that all their actions are governed by hypocrisy. Superstitious prejudices, and respect for a religion which appears more awful from the great bulk of the people being ignorant of its tenets; fear, perhaps, of incantations, and the great respect shewn towards each other, still tend to keep up the popular belief that a Hadji must be a being superior in virtue and sanctity; and if he ever proves the contrary, no one is bold enough to accuse him, as the whole body would then become the enemy of the accuser. It is much the same with the Olemas in Turkey and Arabia; their real character is well known; but they continue to enjoy great credit, because no one likes to be the first to raise his hand against them; and they are protected by the government, which finds them useful in enslaving the multitude, and in directing public opinion.
