Bowing

When everything exists within your big mind, all dualistic relationships drop away. There is no distinction between heaven and earth, man and woman, teacher and disciple. Sometimes a man bows to a woman; sometimes a woman bows to a man. Sometimes the disciple bows to the master, sometimes the master bows to the disciple. A master who cannot bow to his disciple cannot bow to Buddha. Sometimes we may bow to cats and dogs.
