Atharvaveda 5.23

Worked in (óta) for me [are] heaven-and-earth; worked in [is] divine Sarasvatī; worked in for me [are] both Indra and Agni: to the effect "let them (dual) grind up the worm."

O Indra, lord of riches, smite thou the worms of this boy; smitten are all the niggards by my formidable spell (vácas).

What one creeps about his eyes, what one creeps about his nostrils, what one goes to the midst of his teeth—that worm do we grind up.

Of like form two, of various form two, black two, red two; both the brown and the brown-eared, the vulture and the cuckoo (kóka)—they are slain.

The worms that are white-sided, that are black with white arms, and whatever ones are of all forms—those worms we grind up.

Up in the east goes the sun, seen of all, slayer of the unseen, slaying both those seen and those unseen, and slaughtering all worms.

The yévāshas, the káshkashas, the stirrers, the çipavitnukás—both let the seen worm be slain, and let the unseen be slain.

Slain is the yévāsha of the worms, slain also the nadanimán; I have put them all down, smash (? maṣmaṣā́) like khálva-grains with a millstone.

The three-headed, the three-humped (-kakúd), the variegated, the whitish worm—I crush the ribs of it; I hew at what is its head.

Like Atri I slay you, O worms, like Kaṇva, like Jamadagni; with the incantation of Agastya I mash together the worms.

Slain is the king of the worms, also the chief of them is slain; slain is the worm, having its mother slain, its brother slain, its sister slain.

Slain are its neighbors, slain its further neighbors, also those that are petty, as it were—all those worms are slain.

Both of all worms and of all she-worms I split the head with a stone, I burn the mouth with fire.
