The speculators, the jnanis, go on speculating about the Supreme Personality of Godhead for many, many hundreds of thousands of years, but unless one is favored by the Supreme Personality of Godhead, one cannot understand His supreme glories. All the great sages mentioned in this verse have their planets near Brahmaloka, the planet where Lord Brahma resides along with four great sages–Sanaka, Sanatana, Sanandana and Sanat-kumara. These sages reside in different stars known as the southern stars, which circle the polestar. The polestar, called Dhruvaloka, is the pivot of this universe, and all planets move around this polestar. All the stars are planets, as far as we can see, within this one universe. According to Western theory, all the stars are different suns, but according to Vedic information, there is only one sun within this universe. All the so-called stars are but different planets. Besides this universe, there are many millions of other universes, and each of them contains similar innumerable stars and planets.
