Incidentally, there is also a suggestion that one can attain liberation by bathing in the Ganges. This is again groundless! Dirt on the body cannot keep us in samsara. If mind cannot be cleansed of greed, hate, delusion and clinging to a real self, just keeping the body clean as a crystal would not have anything to do with liberation. What really needs to be cleansed is the alaya consciousness. We will only be able to gain freedom from samsara once the defilements stored in the alaya consciousness have been completely removed.
