Ever seen this pile of stones stacked ?
Each stone in the stack could represent the wish, or maybe even a family member for whom the wishes ask for. It is also believed that some people stack stones as an offering to the gods or as a way of atonement. There's another interesting observation about this practice that I felt and maybe you'll feel it too. Stacking stones on top of each other may look like fun at the first, but slowly you'd be drawn into it
