Introduction to the Buddha's Heart Pond: No matter how the water in the Buddha's Heart Pond changes over time, the depth of the pond will always remain the same. Just like the mind of the Buddha, it will always be impartial, calm, and calm. It faces the wish-listening willow on the opposite side, so it is named Buddha Heart Pond. The water in the pond is spring water. Because there is a spring at the bottom of the pond, the pond water is also called Buddha's Heart Spring.
