My daughter, Jenn, her husband, Matt, and I recently visited the Tucson Botanical Gardens, in Tucson, AZ.
One of the demonstration “rooms” there is a Zen space. In the center is a table where one may do some sand raking. Jenn made this lovely heart and I photographed it and edited on my iPhone.
The minimalist, monochrome, zen heart could be just what you are looking for for your yoga room, a wedding gift, or anniversary card.
