namaste,
As far as I know (by doing some reading and research), aghoris sometimes get their 'bowl' from a river. Around in varanasi and other places/ghats where people either leave the bones etc. in water or leave the whole dead body in water. One aghori I read about claimed to search for a skull for many months in and around the banks of different parts of rivers in varanasi. Finally he got one when the time was right.
