अग्नये स्वाहेत्यग्नौ हुत्वा मन्थे सँस्रवमवनयति सोमाय स्वाहेत्यग्नौ हुत्वा मन्थे सँस्रवमवनयति भूः स्वाहेत्यग्नौ हुत्वा मन्थे सँस्रवमवनयति भुवः स्वाहेत्यग्नौ हुत्वा मन्थे सँस्रवमवनयति
In plain words
'To Agni, hail!' He offers, then lets the last drops fall back into the mixture. 'To Soma, hail!' Again he offers, and again lets the drops fall back. 'Bhūḥ, hail!' The same offering, the same return of the drops. 'Bhuvaḥ, hail!' — and once more, the drops go back into the mantha.
