Perilla said, "Do you know my husband's water and the moon? The deceased is like this, but he has never been there; If you are full of emptiness, the dead will not ebb and flow. Gai must view it from its changers, then heaven and earth can't be in an instant; If we look at it from its unchanging point of view, then things are infinite to me, but why envy them? Besides, between heaven and earth, everything has its own owner, not mine, so I will take it for nothing. However, the breeze on the river and the bright moon in the mountains are empty to the ear and endless in color. It is the creator's endless hiding place, and my son and I are in the right place. "
