Spirals can be found everywhere in Nature, plants, snail shells, seashells, clouds and water paterns, galaxies.... They will represent continual motion and balance. They symbolize the slow reveal of things that are hidden. It can mean growth and evolution. They could represent people coming back to the same point in their life, but with new and better kinds of understanding.
