佛塔, or "stupa," is a mound-like structure that holds relics and is used as a place of meditation in Buddhism. These structures symbolize the enlightened mind of the Buddha and serve as a focal point for worship and reflection. Typically, 佛塔 are built in various styles and sizes, often adorned with intricate carvings and symbols. They can be found in many countries where Buddhism is practiced, including China, Japan, and India, each reflecting local architectural traditions and cultural influences.
