The phrase 'Moss on the dry landscape' refers to a traditional Japanese aesthetic concept that appreciates the beauty found in natural elements that are often overlooked or considered unwelcome, such as moss growing on dry, barren rocks. This concept embodies the beauty of simplicity and the acceptance of natural imperfection. It is a key aspect of the Japanese appreciation of nature and the arts, particularly in the fields of Zen Buddhism, gardening, and the visual arts.
