This is what happens to stones found around out there... You have to turn around the pile 3 times and each time throw a new stone... After a while they become real castles...for Buddha in this case!
Not surprising that Mongolians call the sky the Eternal Blue Sky and place their God right up there. Which such wide spaces you can see the sky all around you. Travelling by 4 wheels (a Russian one...) you always have the sky in front of you...
Have to run for my pedicure, will continue tomorrow ;-)
