Once there was a Zen master who was befriended by a nobleman. Everytime he went to see his friend, the Zen master would go with great pomp and ceremony. He would engage a big retinue and go to his friend's house in a procession.
Once he was going to visit the nobleman when the men in his retinue told him that on the way there was a cobbler who could make wonderful straw sandals and they would like to buy a few pairs from him. The Zen master agreed to make the stop for his men. As they neared the shop, the cobbler himself came out to greet them. When he saw the cobbler, the Zen master was stunned. The cobbler was none other than his teacher, himself a great Zen practitioner.
The Zen master alighted from his palanquin and ran to his master and paid his respects. The the two passed along time together, exchanging news and talking about old times. Finally, when it was time for the Zen master to leave, the cobbler turned to him and said, "Do not let your head be turned by associations with noblemen."
