The Buddha said: Living in the world is like being among thorns. If the heart is not moving, people will not move rashly, and if they are still, they will not be hurt; if the heart is moving, people will be moving rashly, hurting their bodies and bones, and then they will experience all kinds of pain in the world. It's not that she is incomprehensible, it's just that all living beings must experience all kinds of suffering before they can count their experiences in this world in vain.
