"I have heard that Otaké of the Seventh Rank and Wu of the sixth rank once went to a clairvoyant and asked for advice on how to win. The proper method, said the man, was to lose all awareness of self while awaiting an adversary's play. [...] While waiting for a play he [Onoda of the Sixth Rank] would sit quietly with his eyes closed. He explained that he was ridding himself of the desire to win."
