Goloka-nāmni nija-dhāmni. There is a planet in the spiritual world . . . the material world, you can see the material sky, limit of the sky, the horizon, but you are not able to reach even the moon planet, the nearest planet. But within this universe, within this horizon, there are innumerable planets. Aśeṣa. Yasya prabhā prabhavato jagad-aṇḍa-koṭi koṭiṣv aśeṣa-vasudhādi vibhūti-bhinnam (Bs. 5.40). By the shining effulgence from the body of Kṛṣṇa . . . that is called brahma-jyotir.
Within that brahma-jyotir, or effulgence, there are innumerable universes. Ananta-koṭi. Yasya prabhā prabhavato jagad-aṇḍa-koṭi. Koṭi means innumerable. One million . . .ten millions equal to one lakh. Such hundred lakhs makes a koṭi. So actually we see there are innumerable planets, but beyond this creation . . . this is material creation, one-fourth manifestation, one-fourth manifestation of God's creation, this, this material world.
This is also only one universe. There are innumerable universes clustered together, and beyond this clustering of universes there is another sky, which is called paravyoma, or spiritual sky. If you want to go there, then you have to penetrate through the material coverings—earth, water, fire, water . . . fire, air, like that. Each layer so big. And the next layer is ten times more than the first layer. In this way there are seven layers. So penetrating through that seven layers you reach the spiritual sky. And after reaching the spiritual sky, there are so many Vaikuṇṭha planets, spiritual planets.
So that is summarized: goloka-nāmni nija-dhāmni tale ca tasya (Bs. 5.43). The topmost planet is called Goloka, or Kṛṣṇa-, Kṛṣṇaloka. Go means cows. Kṛṣṇa is very much fond of cows. Therefore that planet is called also Goloka, the planet full of cows. We have recited Brahma-saṁhitā today, cintāmaṇi-prakara-sadmasu kalpa-vṛkṣa-lakṣā-vṛteṣu surabhīr abhipālayantam (Bs. 5.29). Kṛṣṇa is engaged in tending cows. He's very much fond of cows. Surabhi. They are not ordinary cows. In the spiritual world, everything is spiritual. So there is a planet, goloka-nāmni. So that is the highest planet. Goloka-nāmni nija-dhāmni. That is the personal abode. Goloka-nāmni nija-dhāmni tale ca tasya (Bs. 5.43). Under that planet, there are other planetary systems. They are called Devī-dhāma, Maheśa-dhāma, Hari-dhāma.
