tadāhurvihṛtā agnayo bhavanti | vāstu pariśiṣyate | garbhā anuśoṣukā

eṣa ha vā udgātuśca yajamānasya ca dhiṣṇyo yadāstāvaḥ

Regarding this they say: 'The fires are distributed; the site is left over; embryos would dry up if one were to pour it into the pit (cātvāla). One should pour it out at the chanting-place (āstāva).' That hearth (dhiṣṇya) of both the Udgātṛ and the sacrificer is indeed the chanting-place; the chanting-place is a support. In this very support they thereby establish these desires. Having poured out as much of them there as desired, one should then pour them inside the enclosure-sticks (paridhi). Thus those [waters] become both offered and unoffered for them. Just as these two known breaths are indistinct, so these two, being hearths, are uncomprehended; being these two breaths, they are unpierced; being these two hearths, they are not distributed.
