CHĀNDOGYA UPANISHAD · 4.7.1

हꣳसस्ते पादं वक्तेति स ह श्वोभूते गा
अभिप्रस्थापयांचकार ता यत्राभि सायं
बभूवुस्तत्राग्निमुपसमाधाय गा उपरुध्य समिधमाधाय
पश्चादग्नेः प्राङुपोपविवेश ॥ ४.७.१॥

haꣳsaste pādaṃ vakteti sa ha śvobhūte gā
abhiprasthāpayāṃcakāra tā yatrābhi sāyaṃ
babhūvustatrāgnimupasamādhāya gā uparudhya samidhamādhāya
paścādagneḥ prāṅupopaviveśa ॥ 4.7.1॥

'A Hamsa (flamingo, meant for the sun) will declare to you another foot of Brahman.' (After these words of Agni), Satyakâma, on the morrow, drove the cows onward. And when they came towards the evening, he lighted a fire, penned the cows, laid wood on the fire, and sat down behind the fire, looking toward the east.
