Hekiganroku - Case 24: Tetsuma, the Cow

Ryu Tetsuma [1] came to Isan. Isan said,
  "Old Cow, you have come!"
Tetsuma said,
  "Tomorrow there will be a great feast at Mt Tai [2].
   Will you go there, Master?"
Isan lay down and stretched himself out. Tetsuma left immediately. 

[1] A famous Zen person, once a student of Isan. Her name means "Ryu, the
    iron grindstone."
[2] More exactly: Mt. Gotai, which is far away in the northern part of
    the country.
