bamboo shoot

emitting light
bamboo shoot was
peeled off

original haiku "筍たけのこの 光ひかり放はなって むかれたり" (converted to modern orthography)
composed by WATANABE Suiha (1882-1946)
roughly translated by the blog owner

This haiku might hint the Japanese oldest story named "Taketori monogatari" in which princess Kaguya was born from a mysterious shining bamboo.
