Case 76: Tanka's "Eating Rice"

Tanka asked a monk,
   "Where have you come from?"
The monk answered,
   "From the foot of the mountain."
Tanka asked,
   "Have you eaten your rice?"
The monk said,
   "Yes I have eaten it." 
Tanka said,
   "The one who brought rice and gave it to you to eat did he have an
    [enlightened] eye?"
The monk said nothing.

Chokei asked Hofuku,
   "Surely it is an act of thanksgiving [1] to bring rice and give it to the
    people to eat. How then is it possible not to have an [enlightened] eye?"
Hofuku said, 
   "Server and receiver are both blind."
Chokei said,
   "Even if one has done everything, does one still remain blind, or not?"
Hofuku said,
   "Do you call me blind?"

     masters.
