1. The original spiritual planet, which resembles the whorl of a huge lotus flower, is called Goloka Vrndavana. It is the abode of Lord Krishna, the original Personality of Godhead.
2. This original planet Goloka throws off a spiritual ray of effulgence called brahmajyoti which is the ultimate goal of the impersonalists.
3. Within this unlimited brahmajyoti there are unlimited numbers of spiritual planets, as there are innumerable material planets within the sun rays of the material universes. These spiritual planets are dominated by plenary expansions of Lord Krishna, and the inhabitants there are ever liberated living beings. They are all four-handed. The Lord is known there as Narayana, and the planets are known as Vaikunthas.
4. Sometimes a spiritual cloud overtakes a corner of the spiritual sky of brahmajyoti, and the covered portion is called the mahat-tattva. The Lord then, by His portion as Maha-Vishnu (Karanodakasayi Visnu), lies down in the water within the mahat-tattva. The water is called the Causal Ocean (karana-jala).
5. As He sleeps within the Causal Ocean, innumerable universes are generated with His breathing. These floating universes are scattered all over the Causal Ocean. They stay during a breath of Maha-Vishnu.
6. In each and every universal globe the same Maha-Vishnu enters again as Garbhodakasayi Vishnu and lies there on the Garbha Ocean on the serpentine Sesa incarnation. From His navel-abdomen sprouts a lotus stem, and on the lotus, Brahma, the lord of the universe, is born. Brahma creates all living beings of different shapes in terms of desire within the universe. He also creates the sun, moon and other demi-gods.
7. The sun is situated almost in the center of each and every universe, and it distributes profuse light and heat all over the universe. There are millions and billions of suns in all the millions and billions of universes within the mahat-tattva. The suns and moons are required within the universes because they are dark by nature. The Vedas instruct us to go out of the dark universes and reach the glowing effulgence, the brahmajyoti.
8. The brahmajyoti is due to the illuminating Vaikuntha planets, which need no sun or moon or power of electricity. Srimad-Bhagavatam helps us reach the supreme planet, Goloka Vrndavana. The door is open for everyone. Human life is meant for this particular aim, for it is the highest perfection.
