Think about it ~
Shapes and colors affect emotional response. With stone balance, it is the way (im)perfect rocks coalesce to form a perfectly interdependent energetic whole via shapes, colors, curves, and of course, gravity. Some designs seem more resonant than others. That’s about the extent of my understanding for now. But I do know they trigger something in most humans. something deep. perhaps on a soul level, and especially when viewed in three dimensions.
