"No Cold and Heat" by Tozan (Blue Cliff Record Case 43: Dongshan’s Cold and Heat)
A monk asked Tozan: "How can we escape the cold and the heat?"
Tozan replied, "Why not go where there is no cold and heat?"
"Is there such a place?" the monk asked.
Tozan commented, "When cold, be thoroughly cold; when hot, be hot through and through."
