Zen Flesh, Zen Bones is a collection of four books in one. If Zen were so non-Zen as to have canon, this book would be such.

The following three passages are Zen works from the second book, The Gateless Gate, a collection koans from the 13th century.

# Yet in a dream he talks of a dream.
# A monster among monsters,
# He intended to deceive the whole crowd.

    foreach $person (@crowd){

# If the buffalo runs, he will fall into the trench;
# if he returns, he will be butchered.
# That little tail
# Is a very strange thing.

# When the earth is parched rain will fall.
# He opened his heart fully and spoke out,
# But it was useless to talk to pigs and fish.
