Srimad-Bhagavatam: Canto 5 - Chapter 1 - Verse 2
स हि सर्वेषां ज्योतिर्गणानां ग्रहनक्षत्रादीनामनिमिषेणाव्यक्तरंहसा भगवता कालेन भ्राम्यमाणानां स्थाणुरिवावष्टम्भ ईश्वरेण विहित: शश्वदवभासते ॥ २ ॥
sa hi sarveṣāṁ jyotir-gaṇānāṁ graha-nakṣatrādīnām animiṣeṇāvyakta-raṁhasā bhagavatā kālena bhrāmyamāṇānāṁ sthāṇur ivāvaṣṭambha īśvareṇa vihitaḥ śaśvad avabhāsate.
Established by the supreme will of the Supreme Personality of Godhead, the polestar, which is the planet of Mahārāja Dhruva, constantly shines as the central pivot for all the stars and planets. The unsleeping, invisible, most powerful time factor causes these luminaries to revolve around the polestar without cessation.
It is distinctly stated herein that all the luminaries, the planets and stars, revolve by the influence of the supreme time factor. The time factor is another feature of the Supreme Personality of Godhead. Everyone is under the influence of the time factor, but the Supreme Personality of Godhead is so kind and loves His devotee Mahārāja Dhruva so much that He has placed all the luminaries under the control of Dhruva’s planet and has arranged for the time factor to work under him or with his cooperation. Everything is actually done according to the will and direction of the Supreme Personality of Godhead, but to make His devotee Dhruva the most important individual within the universe, the Lord has placed the activities of the time factor under his control.
