"A frog in a well cannot conceive of the ocean."

“How do I know that enjoying life is not a delusion? How do I know that in hating death we are not like people who got lost in early childhood and do not know the way home? Lady Li was the child of a border guard in Ai. When first captured by the state of Jin, she wept so much her clothes were soaked. But after she entered the palace, shared the king's bed, and dined on the finest meats, she regretted her tears. How do I know that the dead do not regret their previous longing for life? One who dreams of drinking wine may in the morning weep; one who dreams weeping may in the morning go out to hunt. During our dreams we do not know we are dreaming. We may even dream of interpreting a dream. Only on waking do we know it was a dream. Only after the great awakening will we realize that this is the great dream. And yet fools think they are awake, presuming to know that they are rulers or herdsmen. How dense! You and Confucius are both dreaming, and I who say you are a dream am also a dream. Such is my tale. It will probably be called preposterous, but after ten thousand generations there may be a great sage who will be able to explain it, a trivial interval equivalent to the passage from morning to night.”

“Right is not right; so is not so. If right were really right it would differ so clearly from not right that there would be no need for argument. If so were really so, it would differ so clearly from not so that there would be no need for argument.”

“The wise man looks into space and does not regard the small as too little, nor the great as too big, for he knows that, there is no limit to dimensions.”

“Of a person who has limited life experience and hence world view; see 井底之蛙.”

“Those in positions of power spend day and night plotting and pondering about what to do. The body is treated in a very careless way. People live their lives, constantly surrounded by anxiety. If they live long before dying, they end up in senility, worn out by concerns: a terrible fate.”

“Perfect happiness is keeping yourself alive, and only actionless action can have this affect.”
