RV 10.28.5
कथा त एतद् अहम् आ चिकेतं गृत्सस्य पाकस् तवसो मनीषाम् । त्वं नो विद्वां ऋतुथा वि वोचो यम् अर्धं ते मघवन् क्षेम्या धूः ॥
kathā ta etad aham ā ciketaṃ gṛtsasya pākas tavaso manīṣām | tvaṃ no vidvāṃ ṛtuthā vi voco yam ardhaṃ te maghavan kṣemyā dhūḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
How shall I solve this riddle, I, the simple, declare the thought of thee the Wise and Mighty? Tell us, well knowing, as befits the season: Whitherward is thy prosperous car advancing?
Translated by Ralph T. H. Griffith (1896)
