Chinese Zen patriarch, Bodhidharuma said this. It is known the word that expressed a state of his realization with a word.　If it compares that it says the ‘kakunen’, it seems to be a blue sky after strong wind blew.　It is extremely by fine weather and a refreshing state. The state does not have dirty hesitation and worldly desires toward cloves either and, on the contrary, does not have even realization.　It is the world of the absolute ‘Empty’ that was beyond all words. Mountain, river, grass, tree, flower, bird, wind, moon, all sentient beings are still brightening life lively in this world.
