There was a minister in olden days who once, when he was Palace
Secretary, was getting ready for office in the morning. He had on
his ceremonial dress. It was rather early, and as he leaned on his
arm-rest for a moment, sleep overcame him. He dreamt, and in the
dream he thought he was mounted and on his journey. He was crossing
the bridge at the entrance to East Palace Street, when suddenly he saw
his mother coming towards him on foot. He at once dismounted, bowed,
and said, "Why do you come thus, mother, not in a chair, but on foot?"
She replied, "I have already left the world, and things are not where
I am as they are where you are, and so I walk."
