The Lord next explained to Sanātana Gosvāmī how the different spiritual planets are situated in the spiritual sky. The spiritual planets are also known as Vaikuṇṭha planets. The planets of the material creation have a limited length and breadth, but as far as the Vaikuṇṭha planets are concerned, because they are spiritual there is no limit to their dimensions. Lord Caitanya informed Sanātana Gosvāmī that the length and breadth of every Vaikuṇṭha planet is thousands of billions of miles—in other words, no one can measure any Vaikuṇṭha planet's actual extent. Each of these planets is unlimitedly expanded, and in each of them the residents are full in all six opulences—wealth, strength, knowledge, beauty, fame and renunciation. The Supreme Personality of Godhead is present in every Vaikuṇṭha planet. Indeed, in each Vaikuṇṭha planet an expansion of Kṛṣṇa has His eternal abode, and Kṛṣṇa Himself has His original eternal abode, called Kṛṣṇaloka or Goloka Vṛndāvana.
In this universe even the largest planet lies in one corner of outer space. For example, although the sun is a million times larger than the earth, it still lies in one corner of outer space. Similarly, each of the Vaikuṇṭha planets, although unlimited in length and breadth, lies in a corner of the spiritual sky, known as the brahmajyoti. In the Brahma-saṁhitā (5.40) the brahmajyoti is described as niṣkalam anantam aśeṣa-bhūtam, or undivided and unlimited and without a trace of the material modes of nature. All the Vaikuṇṭha planets are like petals of a lotus flower, and the principal part of that lotus, the center of all the Vaikuṇṭhas, is called Kṛṣṇaloka or Goloka Vṛndāvana.
Thus the expansions of Kṛṣṇa in various forms, as described herein, as well as His various abodes on the spiritual planets in the spiritual sky, are unlimited. Even demigods like Brahmā and Śiva cannot see the Vaikuṇṭha planets or even estimate their number or vast extent. This is confirmed in Śrīmad-Bhāgavatam (10.14.21): "No one can estimate the length and breadth of all the Vaikuṇṭha planets." Elsewhere in the Bhāgavatam (2.7.41) it is stated that not only are demigods like Brahmā and Śiva unable to make such an estimate, but even Ananta, the incarnation of the Lord's opulence of strength, cannot ascertain any limit to the Lord's potency or to the area of the different Vaikuṇṭha planets.
