20.28

"Furthermore, through wisdom gained from hearing or through the divine eye, one contemplates the vomiting-worms residing in the human body, dwelling where the ten vessels flow. When a person eats, these worms leap upward from the lower vessels into the throat, immediately causing the person to vomit. They produce five kinds of vomiting: first, wind vomiting; second, phlegm vomiting; third, saliva vomiting; fourth, mixed vomiting; and fifth, fly vomiting. If the worms are at peace, they pass smoothly into the abdomen at the opening of the stomach."
