The Subtlety of Empathy and Response is analogized by Chih-i with water and the moon. Water does not rise, nor does the moon descend, and yet the moon in an instant is reflected in all bodies of water. The Buddha does not come, and living beings do not go. It is through the capacities of living beings (who possess the potential to attain Buddhahood) and the response of the Buddha (who exerts kindness and compassion) that two parties are connected.
