Through a series of events, he receives the chance of a lifetime, his dream, to train with the Kung Fu masters. Under the leadership of Master OOgway, who is a mature, old turtle, Po begins his training. Master OOgway is an aged and wise teacher. In one of his most memorable teachings, he says to Po,
