ŚVETĀŚVATARA UPANISHAD · 6.1

स्वभावम् एके कवयो वदन्ति कालं तथान्ये परिमुह्यमानाः ।
देवस्यैष महिमा तु लोके येनेदं भ्राम्यते ब्रह्मचक्रम् ॥

svabhāvam eke kavayo vadanti kālaṃ tathānye parimuhyamānāḥ ।
devasyaiṣa mahimā tu loke yenedaṃ bhrāmyate brahmacakram ॥

Some wise men, deluded, speak of Nature, and others of Time (as the cause of everything ); but it is the greatness of God by which this Brahma-wheel is made to turn.
