Below Rāhu by 10,000 yojanas [80,000 miles] are the planets known as Siddhaloka, Cāraṇaloka and Vidyādhara-loka.
Beneath Vidyādhara-loka, Cāraṇaloka and Siddhaloka, in the sky called antarikṣa, are the places of enjoyment for the Yakṣas, Rākṣasas, Piśācas, ghosts and so on. Antarikṣa extends as far as the wind blows and the clouds float in the sky. Above this there is no more air.
Below the abodes of the Yakṣas and Rākṣasas by a distance of 100 yojanas [800 miles] is the planet earth. Its upper limits extend as high as swans, hawks, eagles and similar large birds can fly.
My dear King, beneath this earth are seven other planets, known as Atala, Vitala, Sutala, Talātala, Mahātala, Rasātala and Pātāla. I have already explained the situation of the planetary systems of earth. The width and length of the seven lower planetary systems are calculated to be exactly the same as those of earth.
In these seven planetary systems, which are also known as the subterranean heavens [bila-svarga], there are very beautiful houses, gardens and places of sense enjoyment, which are even more opulent than those in the higher planets because the demons have a very high standard of sensual pleasure, wealth and influence. Most of the residents of these planets, who are known as Daityas, Dānavas and Nāgas, live as householders. Their wives, children, friends and society are all fully engaged in illusory, material happiness. The sense enjoyment of the demigods is sometimes disturbed, but the residents of these planets enjoy life without disturbances. Thus they are understood to be very attached to illusory happiness.
My dear King, in the imitation heavens known as bila-svarga there is a great demon named Maya Dānava, who is an expert artist and architect. He has constructed many brilliantly decorated cities. There are many wonderful houses, walls, gates, assembly houses, temples, yards and temple compounds, as well as many hotels serving as residential quarters for foreigners. The houses for the leaders of these planets are constructed with the most valuable jewels, and they are always crowded with living entities known as Nāgas and Asuras, as well as many pigeons, parrots and similar birds. All in all, these imitation heavenly cities are most beautifully situated and attractively decorated.
The parks and gardens in the artificial heavens surpass in beauty those of the upper heavenly planets. The trees in those gardens, embraced by creepers, bend with a heavy burden of twigs with fruits and flowers, and therefore they appear extraordinarily beautiful. That beauty could attract anyone and make his mind fully blossom in the pleasure of sense gratification. There are many lakes and reservoirs with clear, transparent water, agitated by jumping fish and decorated with many flowers such as lilies, kuvalayas, kahlāras and blue and red lotuses.
Pairs of cakravākas and many other water birds nest in the lakes and always enjoy in a happy mood, making sweet, pleasing vibrations that are very satisfying and conducive to enjoyment of the senses.
Since there is no sunshine in those subterranean planets, time is not divided into days and nights, and consequently fear produced by time does not exist.
Many great serpents reside there with gems on their hoods, and the effulgence of these gems dissipates the darkness in all directions.
Since the residents of these planets drink and bathe in juices and elixirs made from wonderful herbs, they are freed from all anxieties and physical diseases. They have no experience of grey hair, wrinkles or invalidity, their bodily lusters do not fade, their perspiration does not cause a bad smell, and they are not troubled by fatigue or by lack of energy or enthusiasm due to old age.
They live very auspiciously and do not fear death from anything but death's established time, which is the effulgence of the Sudarśana cakra of the Supreme Personality of Godhead.
When the Sudarśana disc enters those provinces, the pregnant wives of the demons all have miscarriages due to fear of its effulgence.
