Read the following context and answer the question.
Context: The strange process of expulsion resumed , the hill peaking high with a pulsing movement and the skin tearing open .

Again the emergence stopped and the rent began to heal , though the protrusion did n't retreat .
Question: What is the reason Manji bit down on a peeled stick ?
Answer:


Biting a stick was a way to forget the pain being felt .
