6. He then takes some (of the ashes) therefrom: he thereby reproduces from the waters what there is of Agni’s nature in that (heap of ashes). [He takes it] with that (nameless or little finger), for with that (finger) medicine is prepared: it is with that one he thus puts him (Agni) together. [Vajasaneyi Samhita XII, 38-41] “Having settled in the womb, as ashes, in the waters, and the earth, O Agni,”—by his ashes he is, indeed, settled in the womb, that is, both in the waters and in the earth;—“having united with the mothers, thou hast again, brightly shining, seated thee;”—that is, “Having joined thy mothers, thou, the shining one, hast again seated thyself (in thy home).”—“Having again seated thee in thy seat, the waters and the earth, O Agni, thou liest in her (the earth, or pan) most happy, as in a mother’s lap.”—“Return again with sustenance, again, O Agni, with food and life; guard us again from trouble!—With wealth return, O Agni, overflow with the all-feeding stream on every side!”—that is, “With all this return thou to me!”
