Kyu do mugen (There is no end to seeking/learning the way): there is no end to seeking or learning. Even at advanced levels, there are still higher levels to reach. There is no point at which one's skill or understanding is complete. Learning "the way" is done day by day, minute by minute, second by second, now, to eternity. There is no faster way.
