One interesting note is that there are few or no flowers or fountains in this garden, nor in most such gardens. These gardens are contemplations on Rock, Water (still), Sand and Moss (vegetation). The art is in achieving the atmosphere of peace and tranquility, and a look as of nature perfected, with minimal use of tools or devices. All of it must fit into a limited space, as they are originally intended for the grounds of people of some wealth, but not emperors or kings.
