Why are there zen gardens?

Zen gardens, also known as Japanese rock gardens or karesansui, are designed to promote meditation and reflection. They typically feature carefully arranged rocks, gravel, and minimal vegetation, symbolizing natural landscapes in a simplified form. The raked patterns in the gravel are meant to represent water ripples, encouraging mindfulness and a sense of tranquility. These gardens serve as spaces for contemplation, allowing individuals to connect with nature and find inner peace.
