Śatapatha Brāhmaṇa ("of a hundred paths") 2.3.3.10

2.3.3.10

yathā vā iṣoranīkam | evaṃ yajñānāmagnihotraṃ yena vā iṣoranīkameti sarvā vai teneṣuretyeteno hāsya sarve yajñakratava etam mṛtyumatimuktāḥ

What the arrow-head is to the arrow, that the Agnihotra is to sacrifices. For whither the head of the arrow flies, thither the whole arrow flies: and so are all his works of sacrifice freed by this (Agnihotra) from that Death.
