治禪病祕要法 1.54

1.54

"In each of the ninety-nine layers there are four hundred and four worms, each worm having twelve heads and twelve mouths. When a person drinks water, the essence of the water enters the channels and is dispersed to the various worms, entering the head of the vīra worm straight to the birth canal; every half month it discharges impure fluid, each worm vomiting like putrid pus; entering the mouths of ninety worms, it emerges from the six orifices of twelve worms like putrid red juice. Furthermore, there are worms finer than an autumn down frolicking within it.
