菩薩從兜術天降神母胎說廣普經 2.20

2.20

「吾昔無數阿僧祇劫修身神通，分別身中淨不淨想、不淨淨想，三十六物污露不真，髮、毛、爪、齒、骨、血、涕、淚，反復思惟；以己身法觀眾生身亦復如是。自化其身膖脹臭爛膿血流出；或復現身白骨灰色、青瘀色、燋黑色、與地同色，無量眾生見此身者，皆生苦、空、無常、無我想。復與眾生說身業報法，此身非身何者是身？一一分別從頭至足悉無所有，以無有身則無有識。眾生聞此，自思惟身穢惡不淨，猶如光音清淨天下觀閻浮提臭穢，惡氣上熏七千萬里，是以菩薩不生光音天。身通菩薩入金剛三昧碎身如塵，一一塵皆作化佛，濟渡無量阿僧祇眾生之類；現身色相，身上出火身下出水，身下出火身上出水，東踊西沒西踊東沒；現如來十八神變。眾生之類見如來變尋時覺悟，眾結永盡入無為道。微塵化佛現身教化，濟渡無量阿僧祇眾生，是為如來身密教化而不說法。

"In the past, for countless asaṃkhyeya kalpas, I cultivated the divine faculty of the body, distinguishing perceptions of pure and impure, and of impure and pure within the body: thirty-six impure, foul, and untrue substances—hair of the head, hair of the body, nails, teeth, bones, blood, snot, and tears—contemplating them repeatedly; and using the nature of one's own body, one contemplates the bodies of sentient beings as being likewise. I manifested my own body as swollen, bloated, rotting with foul stench, with pus and blood flowing out; or again manifested the body as white bones of ashen color, bluish-bruised color, charred-black color, or of the same color as the earth. When immeasurable sentient beings saw this body, they all gave rise to perceptions of suffering, emptiness, impermanence, and non-self. Furthermore, I expounded to sentient beings the Dharma of the bodily karmic retributions: 'This body is not a body; what is the body? Distinguishing each part one by one from head to foot, none of it exists at all. Because there is no body, there is no consciousness.' When sentient beings heard this, they contemplated their own bodies as vile and impure, just as the pure gods of the Ābhāsvara Heaven look down and see Jambudvīpa as foul and impure, its noxious vapors rising seventy million li—for this reason, bodhisattvas are not born in the Ābhāsvara Heaven. A bodhisattva possessing the divine faculty of the body enters the vajrasamādhi and crushes his body into dust, each and every speck of dust turning into a transformation Buddha, delivering immeasurable asaṃkhyeyas of kinds of sentient beings; manifesting the physical marks of his body, fire issues from the upper body and water issues from the lower body, fire issues from the lower body and water issues from the upper body, leaping up in the east and sinking down in the west, leaping up in the west and sinking down in the east; displaying the Tathāgata's eighteen miraculous transformations. When all kinds of sentient beings behold the Tathāgata's transformations, they immediately awaken, their numerous fetters are eternally extinguished, and they enter the unconditioned Path. Specks of dust as transformation Buddhas manifest bodies to instruct and transform, delivering immeasurable asaṃkhyeyas of sentient beings. This is the Tathāgata's secret teaching through the body without preaching the Dharma.
