If one flies in outer space he can go very high up, but unless he reaches a planet he must come down again to earth. Similarly, because the impersonalists who reach the paraṁ padam of the impersonal brahmajyoti do not enter into the Vaikuṇṭha planets, they come down again to this material world and are given shelter in one of the material planets. Although they may attain Brahmaloka, or Satyaloka, all such planets are situated in the material world.
