The development and characteristics of Zen rock garden

Quick answer：

Zen rock gardens, also known as karesansui, originated in Japan and have evolved over centuries. They are characterized by their minimalist design, typically using rocks, sand, and moss to represent landscapes. Key characteristics include the use of natural elements to evoke a sense of tranquility and the absence of water, symbolizing the fluidity and changeability of life. The gardens often feature a central focal point, such as a rock or a group of rocks, and are designed to encourage contemplation and meditation.
