Stressed out with your job, partner or life in general? A real Zen garden would the best way to find your inner peace but Japan is way too far. So you can have your own small Japanese Rock Garden in the form of Jigsaw Puzzle. No sand is included because it is a puzzle but you will get four types of actual rocks included and moss matting . Don’t be upset about buying rocks, it is not zen like. That is the first test.
