CHĀNDOGYA UPANISHAD · 3.19.3

अथ यत् तद् अजायत सो ऽसाव् आदित्यः ।
तं जायमानं घोषा उलूलवो ऽनूदतिष्ठन्त् सर्वाणि च भूतानि सर्वे च कामाः ।
तस्मात् तस्योदयं प्रति प्रत्यायनं प्रति घोषा उलूलवो ऽनूत्तिष्ठन्ति सर्वाणि च भूतानि सर्वे च कामाः ॥

atha yat tad ajāyata so ’sāv ādityaḥ ।
taṃ jāyamānaṃ ghoṣā ulūlavo ’nūdatiṣṭhant sarvāṇi ca bhūtāni sarve ca kāmāḥ ।
tasmāt tasyodayaṃ prati pratyāyanaṃ prati ghoṣā ulūlavo ’nūttiṣṭhanti sarvāṇi ca bhūtāni sarve ca kāmāḥ ॥

And what was born from it that was Âditya, the sun. When he was born shouts of hurrah arose, and all beings arose, and all things which they desired. Therefore whenever the sun rises and sets, shouts of hurrah arise, and all beings arise, and all things which they desire.
