Library·Chāndogya Upaniṣad·3·3.4
अथ ये ऽस्योदञ्चो रश्मयस् ता एवास्योदीच्यो मधुनाड्यः । अथर्वाङ्गिरस एव मधुकृतः । इतिहासपुराणं पुष्पम् । ता अमृता आपः
atha ye 'syodañco raśmayas tā evāsyodīcyo madhunāḍyaḥ | atharvāṅgirasa eva madhukṛtaḥ | itihāsapurāṇaṃ puṣpam | tā amṛtā āpaḥ
The northern rays of the sun are the honey-cells on the left. The (hymns of the) Atharvângiras are the bees, the Itihâsa-purâna (the reading of the old stories) is the flower, the water is the nectar.
Translated by F. Max Müller
ते वा एते ऽथर्वाङ्गिरस एतद् इतिहासपूराणम् अभ्यतपन् । तस्याभितप्तस्य यशस् तेज इन्द्रियां वीर्यम् अन्नाद्यं रसो ऽजायत
te vā ete 'tharvāṅgirasa etad itihāsapūrāṇam abhyatapan | tasyābhitaptasya yaśas teja indriyāṃ vīryam annādyaṃ raso 'jāyata
Those very hymns of the Atharvângiras (as bees) brooded over the Itihâsa-purâna; and from it, thus brooded on, sprang as its (nectar) essence, fame, glory of countenance, vigour, strength, and health.
Translated by F. Max Müller
तद् व्यक्षरत् । तद् आदित्यम् अभितो ऽश्रयत् । तद् वा एतद् यद् एतद् आदित्यस्य परःकृष्णं रूपम्
tad vyakṣarat | tad ādityam abhito 'śrayat | tad vā etad yad etad ādityasya paraḥkṛṣṇaṃ rūpam
That flowed forth, and went towards the sun. And that forms what we call the extreme dark (parah krishnam) light of the sun.
Translated by F. Max Müller
