The Zen Garden is a place to get away and relax for a few minutes or hours. It's a place to enter into a meditative state and feel the peace of the world around you. However, if the garden is not maintained, it will quickly become overgrown and lose its balance. This can cause an individual to jump out of their peaceful state and back into reality, which isn't always pleasant.
Zen gardens are important because they provide us with an opportunity to take time for ourselves while also keeping our minds balanced and focused on what we need in life.
