[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. [Vâg. S. 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!'
