Chinese Zen patriarch,Bodhidharuma (d.532) said this word.
  It make the “kekka jinenn jyou” and a couplet.  A person has one flower in own heart. The floral art founded five petals. Nothing that the way cut out that you wanted to know a meaning of "five petals" .  You practice Zen.  Yourself search a heart deeply and cannot but acquire the meaning by experience by own self through hardships.  The practice gives your heart beauty and must make your life limitless wealthily.
