yasyaikaṁ cakraṁ dvādaśāraṁ ṣaṇ-nemi tri-ṇābhi saṁvatsarātmakaṁ samāmananti tasyākṣo meror mūrdhani kṛto mānasottare kṛtetara-bhāgo yatra protaṁ ravi-ratha-cakraṁ taila-yantra-cakravad bhraman mānasottara-girau paribhramati.
Kereta Dewa Surya hanya mempunyai satu roda, dikenali sebagai Saṁvatsara. Dua belas bulan ialah dua belas jejari, enam musim ialah bahagian-bahagian rim, dan tiga tempoh cātur-māsya ialah hab yang terbahagi tiga. Satu hujung gandar bertumpu di puncak Gunung Sumeru dan satu lagi di Gunung Mānasottara; roda yang terpasang pada hujung luar gandar itu berputar tanpa henti di Mānasottara seperti roda mesin pemerah minyak.
This verse describes the year as a single cosmic wheel with twelve spokes, six rims, and three hubs—an image showing time’s structured, divinely governed cycles.
He uses Meru as the fixed axle-point and Mānasottara as the boundary-support to explain, in Purāṇic cosmology, how the Sun’s chariot-wheel is situated and how the Sun is said to circle in a continuous orbit.
Seeing time as an ordered cycle helps one live with discipline and devotion—aligning daily and yearly routines with remembrance of Bhagavān rather than being driven by anxiety and randomness.
