Vṛṣaśuṣmo ha Vātāvata uvāca Jātūkarṇyo:
vaktā smo vā idaṃ devebhyo,
yad vai tad agnihotram ubhayedyur ahūyatānyedur vāva tad etarhi hūyata ity
etad u hovāca= kumārī gandharvagṛhītā:
vaktā smo vā idam pitṛbhyo,
yad vai tad agnihotram ubhayedyur ahūyatānyedur vāva tad etarhi hūyata ity
etad vā agnihotram anyedyur hūyate,
yad astamite sāyaṃ juhoty anudite prātar.
athaitad agnihotram ubhayedyur hūyate,
yad astamite sāyaṃ juhoty udite prātas
tasmād udite hotavyaṃ
caturviṃśe ha vai saṃvatsare 'nuditahomi
gāyatrīlokam āpnoti dvādaśa udītahomi.
sa yadā dvau saṃvatsarāv anudite juhoty atha hāsyaiko huto bhavaty,
atha ya udile juhoti saṃvatsareṇaiva saṃvatsaram āpnoti
ya evaṃ vidvān udite juhoti.
tasmād udite hotavyam
eṣa ha vā ahorātrayos tejasi juhoti yo 'stamite sāyaṃ juhoty udite prātar.
Agninā vai tejasā rātris tejasvaty, Ādityena tejasāhas tejasvad
ahorātrayor hāsya tejasi hutam bhavati ya evaṃ vidvān udite juhoti
tasmād udite hotavyam

v. 29 (xxv. 4) Vṛṣaçuṣma Vātāvata Jātūkarṇya said ‘We shall declare this to the gods; the Agnihotra which used to be performed on both days is now performed on alternate days only’. This also said a maiden seized by a Gandharva ‘We shall declare this to the fathers; the Agnihotra which used to be performed on both days is now performed on alternate days only.’ The Agnihotra is offered on alternate days in that one offers it on the evening after sunset and in the morning before sunrise. The Agnihotra is offered on both days in that one offers it in the evening after sunset and in the morning after sun rise. Therefore the offering should be made after sun rise. He who offers before sunrise obtains the world of the Gāyatrī in the twenty-fourth year; in the twelfth he who offers after sunrise. If he offers for two years before sunrise then he has really sacrificed for one only; he who sacrifices after sunrise with the year obtains the year, he who knowing thus offers after sunrise. Therefore should one offer after sunrise. He offers in the brilliance of day and night who offers in the evening after sunset and in the morning after sunrise. By Agni as brilliance the night is brilliant, by Āditya as brilliant the day is brilliant.

In the brilliance of day and night does he offer who knowing thus offers after sunrise. Therefore should one offer after sunrise .
