According to a Zen Buddhist legend, Buddha twirled a flower in one of his sermons but no one understood the meaning of his gesture except for Mahakasyapa (one of the disciples of Buddha), who grasped the meaning of Buddha's wordless sermon and broke into a smile.
禅宗は、釈迦が華を拈（ひね）り、大衆の中で大迦葉だけがその意味を悟って破顔微笑（はがんびしょう）した。
