If you are in Boston and in need of a little serenity and beauty, the Japanese Garden at the Museum of Fine Arts is a perfect spot to rest for a bit, away from the busy world. I can imagine a half hour of reflection and relaxation, sitting on a bench while eating lunch in the peaceful garden.
Another name for the MFA Japanese Garden, Tenshin-en is "Garden of the Heart of Heaven". As you walk or sit in the contemplative garden, you will feel how apt the alternate name is.
