Zen is a school of Buddhism that is over fifteen hundred years old. It's both a religious practice and a way of life. If they're a person who loves meditative relaxation, or if they're a person who would get a lot out of a calming ritual, discover a gift idea that they'll love. Find the zen garden or other metaphysical zen present that will help them achieve a state of peace. It's a thoughtful gift that will make their day to day lives that much happier.
