Furthermore, a practitioner, observing the body internally according to the body, by means of wisdom gained from hearing or by means of the divine eye, sees ten kinds of worms moving through the marrow, which move in the semen. What are the ten? The first is named the hairy worm; the second is named the black-mouthed worm; the third is named the powerless worm; the fourth is named the great-pain worm; the fifth is named the anguish worm; the sixth is named the fire worm; the seventh is named the slippery worm; the eighth is named the downward-flowing worm; the ninth is named the genital-arousing worm; the tenth is named the mindful-delight worm. If these ten worms become angry contrary to their nature, they also harm the human body. It is fully as explained in the sūtra and cannot be recounted in full.
