ananta vaikuṇṭha-brahmāṇḍa — sabāra āśraya
Through calculation and meditation, the all-knowing astrologer saw the greatly effulgent body of the Lord, which is the resting place of all the unlimited Vaikuṇṭha planets.
Here we get some information of the Vaikuṇṭha world, or spiritual world. Vaikuṇṭha means “without anxiety.” In the material world, everyone is full of anxiety, but another world, where there is no anxiety, is described in the Bhagavad-gītā (8.20):
yaḥ sa sarveṣu bhūteṣu naśyatsu na vinaśyati
“Yet there is another unmanifest nature, which is eternal and is transcendental to this manifested and unmanifested matter. It is supreme and is never annihilated. When all in this world is annihilated, that part remains as it is.”
As there are many planets within the material world, there are many millions of planets, called Vaikuṇṭhalokas, in the spiritual world. All these Vaikuṇṭhalokas, or superior planets, rest on the effulgence of the Supreme Personality of Godhead. As stated in the Brahma-saṁhitā (yasya prabhā prabhavato jagad-aṇḍa-koṭi-), the Brahman effulgence emanating from the body of the Supreme Lord creates innumerable planets in both the spiritual and material worlds; thus these planets are creations of the Supreme Personality of Godhead. The astrologer saw Śrī Caitanya Mahāprabhu to be the very same Personality of Godhead. We can just imagine how learned he was, yet he was traveling door to door, just like an ordinary beggar, for the highest benefit of human society.
