Kakua visited China and accepted the true teaching. He did not travel while he was there. Meditating constantly, he lived on a remote part of a mountain. Whenever people found him and asked him to preach he would say a few words and then move to another part of the mountain where he could be found less easily.
The emperor heard about Kakua when he returned to Japan and asked him to preach Zen for his edification and that of his subjects.
Kakua stood before the emperor in silence. He then produced a flute from the folds of his robe, and blew on
e short note. Bowing politely, he disappeared.
