I think that this means that somehow those stones are created overnight. I can not imagine room for 2000 or 3000 stones.
I think this is why a lot of people have been asking where all these stones come from. I was looking at the pictures several time. Even the gallbladder can not store more then about 40-50 stones. I consider to be stones only those ones which size is at least 1cm. I have flushed at least 100 stones in the last 7-8 months in my 6 liver flushes. Those stones couldn't been there because if the size. I think.
