The Fragrance of the Rose

The disciples were absorbed in a discussion of Lao-tzu’s dictum:
"Those who know, do not say;
Those who say, do not know."
When the master entered,
they asked him what the words meant.
Said the master, "Which of you knows the fragrance of a rose?"
All of them indicated that they knew.
Then he said, "Put it into words."
All of them were silent.
