Chuang Tzu told the story of the autumn floods: The autumn floods had come. Thousands of wild torrents poured furiously into the Yellow River. It surged and flooded its banks until, looking across, you could not tell an ox from a horse on the other side. Then the River God laughed, delighted to think that all the beauty in the world had fallen into his keeping. So downhill he swung, untill he came to the ocean. There he looked out over the waves towards the empty horizon in the east, and his face fell. Gazing out at the far horizon, he came to his senses and murmured to the Ocean God: “Well, proverb is right: ‘He who has got himself a hundred ideas, he thinks he knows more than anybody else.’ Such a one am I. Only now do I see what they mean by expanse!” The Ocean God replied, “Can you talk about the sea to a frog in a well? Can you talk about ice to a dragonfly? And can you talk about the Way of life to a doctor of philosophy?”
