治禪病祕要法 1.27

1.27

"Having contemplated the joints, next contemplate the skull: under each and every hair there are four hundred and four channels entering directly into the brain. The rest of the thin skin, thick skin, and bones are no different from the body, except that there are fourteen layers of brain membrane, the brain is divided into four parts, ninety-eight layers, with the four hundred and four channels flowing into the heart. The large intestine, small intestine, spleen, kidneys, liver, lungs, heart, gallbladder, throat, pulmonary fat, the two receptacles of the digested and undigested, and the eighty thousand families of worms—contemplate each and every one clearly, causing them all to become empty, dazzlingly white and pure, layer of skin wrapping layer of skin, clear and bright in between like white vaiḍūrya."
