There was one who was enlightened with the sound of a bamboo being struck, and another who clarified his mind upon seeing peach blossoms.

Is the bamboo bright or dull, deluded or enlightened? Are peach blossoms shallow or deep, wise or foolish?

Although flowers blossom year after year, not everyone who sees them is enlightened. When a bamboo cracks, not everyone who hears it realizes the way.
