2.36

"He must quickly hold the mind, visualizing the three hundred and thirty-six joints as vajra mountains, lovely in appearance, surpassing Mount Sumeru, which earth, water, fire, and wind cannot shake, seeing only the four snakes holding maṇi jewels in their mouths among the bone mountains. At that time, he should first visualize the shadow of the Buddha, seeing the vajra boundary, where at the tip of a vajra banner there is a maṇi mirror, and the shadows of the seven past Buddhas appear reflected in the mirror. Furthermore, he should carefully contemplate the white ūrṇā between the eyebrows of Vipaśyin Buddha, the white ūrṇā between the eyebrows of Śikhin Buddha, the white ūrṇā between the eyebrows of Tiṣya Buddha, the white ūrṇā between the eyebrows of Krakucchanda Buddha, the white ūrṇā between the eyebrows of Kanakamuni Buddha, the white ūrṇā between the eyebrows of Kāśyapa Buddha, and the white ūrṇā between the eyebrows of Śākyamuni Buddha, seeing that the white ūrṇās between the eyebrows of the seven Buddhas are like crystal, their water extremely pure and cool, washing between the joints. The three hundred and thirty-six joints, washed by the water of the white ūrṇās, become dazzlingly white, pure, and exquisite, like crystal mirrors, beyond compare.
