KAṬHA UPANISHAD · 2.1.9

यतश्चोदेति सूर्योऽस्तं यत्र च गच्छति ।
तं देवाः सर्वेऽर्पितास्तदु नात्येति कश्चन । एतद्वै तत् ॥ ९॥

yataścodeti sūryo’staṃ yatra ca gacchati ।
taṃ devāḥ sarve’rpitāstadu nātyeti kaścana । etadvai tat ॥ 9॥

He from whom the sun riseth and to whom the sun returneth, and in Him are all the Gods established, — none passeth beyond Him. This is the thing thou seekest.
