Guest: Sensei, please tell me about the the essence of cuisine.
Kitaooji: It is something you produce in order to eat.
Guest: So we produce cuisine in order to eat. Then, sensei, what it is that we eat for?
Kitaooji: We eat in order to live.
Guest: Then what do we live for?
Kitaooji: We live in order to die.
If you simplify this into a formula: to cook => to eat => to live => to die. In other words, we cook in order to die.
