SB 4.12.39

Each and every planet within the universe travels at a very high speed. From a statement in Srimad-Bhagavatam it is understood that even the sun travels 16,000 miles in a second, and from Brahma-samhita we understand from the sloka, yac-caksur esa savita sakala-grahanam, that the sun is considered to be the eye of the Supreme Personality of Godhead, Govinda, and it also has a specific orbit within which it circles. Similarly, all other planets have their specific orbits. But together all of them encircle the Pole Star, or Dhruvaloka, where Dhruva Maharaja is situated at the summit of the three worlds. We can only imagine how highly exalted the actual position of a devotee is, and certainly we cannot even conceive how exalted is the position of the Supreme Personality of Godhead.
