"There are sacred rivers also — the Ganges, for example. The idea is that some great person of old has magnetised the source of the river with such powder that all the water that henceforth flows out from that source is in a true sense holy water, bearing with it his influence and his blessing. This is not an impossibility, though it would require either a great reserve of power in the beginning or some arrangement for a frequent repetition. The process is simple and comprehensible... what would be beyond the power of the ordinary man might possibly be quite easy to some one at a much higher level."
