Naraka is the Hindu counterpart of Christian Hell and Islamic Dozakh
This place acts as a purgatory for the souls who have committed the most abominable actions on the earthly plane. Unlike the Eternal Hell of Western religions though, this place is temporary and once the soul has learnt its lesson, it is free to move back into the regular dimension.
There are 28 different hells described in the Vedic literature and these planets are:
Raurav, Sukar, Rodha, Tal, Vishsan, Mahajwal, Taptakumbh, Lavan, Vilohit, Rudhiramabh, Vaitarni, Krimish, Krimibhojan, Asipatravana, Krishna, Lalabhaksha, Darun, Puyuvah, Pap, Vahnijwal, Adhahshira, Sandansh, Kalsutra, Tamas, Avichi, Swabhojan, Apratishthit andAprachi.
The Bhagavata Purana describes Naraka as beneath the earth: between the seven realms of the underworld (Patala) and the Garbhodaka Ocean, which is the bottom of the universe.
It is located in the South of the universe. Pitrloka, where the dead ancestors (Pitrs) headed by Agniṣvāttā reside, is also located in this region.
Yama, (Surya Putra) the Lord of Naraka, resides in this realm with his assistants.
The Devi Bhagavata Purana mentions that Naraka is the southern part of universe, below the earth but above Patala.
The Vishnu Purana mentions that it is located below the cosmic waters at the bottom of the universe.
The Hindu epics too agree that Naraka is located in the South, the direction which is governed by Yama and is often associated with Death.
Pitrloka is considered as the capital of Yama, from where Yama delivers his justice
The ancient sages have made provisions of expiation for those sinners who feel guilty in their conscience after committing their sins. Only those sinners who do not expiate for their sins fall into these hells. Although life here seems to go on for an eternity, in actual fact the duration of one's Karmic sentence here may be only seconds or moments. ]
The god of Death, Yama, employs Yama-dutas (messengers of Yama) or Yama-purushas, who bring souls of all beings to Yama for judgement. Generally, all living beings, including humans and animals, go to Yama's abode upon death where they are judged.
However, very virtuous beings are taken directly to Svarga (heaven). People devoted to charity, especially donors of food, and eternal truth speakers are spared the justice of Yama's court. War-heroes who sacrifice their life and people dying in holy places likeKurukshetra are also described as avoiding Yama. Those who get moksha (salvation) also escape from the clutches of yamadutas. Those who are generous and ascetics are given preferential treatment when entering Naraka for judgement. The way is lighted for those who donated lamps, while those who underwent religious fasting are carried by peacocks and geese.
Yama, as Lord of Justice, is called Dharma-raja. Yama sends the virtuous to Svarga to enjoy the luxuries of paradise. He also assesses the vices of the dead and accords judgement, assigning them to appropriate hells as punishment commensurate with the severity and nature of their sins. A person is not freed of samsara (the cycle of birth-death-rebirth) and must take birth again after his prescribed pleasure in Svarga or punishment in Naraka is over.
Yama is aided by his minister Chitragupta, who maintains a record of all good and evil actions of every living being. Yama-dhutas are also assigned the job of executing the punishments on sinners in the various hells.
Naraka, as a whole, is known by many names conveying that it is the realm of Yama. Yamālaya, Yamaloka, Yamasādana and Yamalokāya mean the abode of Yama. Yamakṣaya (the akṣaya of Yama) and its equivalents like Vaivasvatakṣaya use pun for the word kṣaya, which can be mean abode or destruction. It is also called Saṃyamanī, "where only truth is spoken, and the weak torment the strong", Mṛtyulokāya – the world of Death or of the dead and the "city of the king of ghosts", Pretarājapura.
Some texts mention 7 hells: Put ("childless", for the childless), Avichi ("waveless", for those waiting for reincarnation), Samhata ("abandoned", for evil beings), Tamisra ("darkness", where darkness of hells begin), Rijisha ("expelled", where torments of hell begin), Kudmala ("leprous", the worst hell for those who are going to be reincarnated) and Kakola ("black poison", the bottomless pit, for those who are eternally condemned to hell and have no chance of reincarnation).
The Manu Smriti mentions 21 hells:
Tamisra, Andhatamisra, Maharaurava, Raurava, Kalasutra, Mahanaraka, Samjivana, Mahavichi, Tapana, Sampratapana, Samhata, Sakakola, Kudmala, Putimrittika, Lohasanku, Rijisha, Pathana, Vaitarani, Salmali, Asipatravana and Lohadaraka.
The Yajnavalkya Smriti also lists twenty-one: Tamisra, Lohasanku, Mahaniraya, Salamali, Raurava, Kudmala, Putimrittika, Kalasutraka, Sanghata, Lohitoda, Savisha, Sampratapana, Mahanaraka, Kakola, Sanjivana, Mahapatha, Avichi, Andhatamisra, Kumbhipaka, Asipatravana and Tapana.
The Bhagavata Purana, the Vishnu Purana and the Devi Bhagavata Purana enlist and describe 28 hells; however, they end the description by stating that there are hundreds and thousands of hells.
The Bhagavata Purana enumerates the following 28: Tamisra, Andhatamisra, Raurava, Maharaurava, Kumbhipaka, Kalasutra, Asipatravana, Sukaramukha, Andhakupa, Krimibhojana, Samdamsa, Taptasurmi, Vajrakantaka-salmali, Vaitarani, Puyoda, Pranarodha, Visasana, Lalabhaksa, Sarameyadana, Avichi, Ayahpana, Ksharakardama, Raksogana-bhojana, Sulaprota, Dandasuka, Avata-nirodhana, Paryavartana and Suchimukha.
The Devi Bhagavata Purana agrees with theBhagavata Purana in most of names; however, a few names are slightly different. Taptasurmi, Ayahpana, Raksogana-bhojana, Avata-nirodhana, Paryavartana are replaced by Taptamurti, Apahpana, Raksogana-sambhoja, Avatarodha, Paryavartanataka respectively.
The Vishnu Purana mentions the 28 in the following order: Raurava, Shukara, Rodha, Tala, Visasana, Mahajwala, Taptakumbha, Lavana, Vimohana, Rudhirandha, Vaitaraní, Krimiśa, Krimibhojana, Asipatravana, Krishna, Lalabhaksa, Dáruńa, Púyaváha, Pápa, Vahnijwála, Adhośiras, Sandansa, Kalasutra, Tamas, Avichi, Śwabhojana, Apratisht́ha, and another Avichi.
The summary of twenty-eight hells described in the Bhagavata Purana and the Devi Bhagavata Purana are as follows:
It is intended for a person who grabs another's wealth, wife or children. In this dark realm, he is bound with ropes and starved without food or water. He is beaten and reproached by Yamadutas till he faints.
Here, a man – who deceives another man and enjoys his wife or children – is tormented to the extent he loses his consciousness and sight. The torture is described as cutting the tree at its roots.
Raurava (fearful or hell of rurus):
As per the Bhagavata Purana and the Devi Bhagavata Purana, it is assigned for a person who cares about his own and his family's good, but harms other living beings and is always envious of others. The living beings hurt by such a man take the form of savage serpent-like beasts called rurus and torture this person. The Vishnu Purana deems this hell fit for a false witness or one who lies.
A person who indulges at the expense of other beings is afflicted with pain by fierce rurus calledkravyadas, who eat his flesh.
Kumbhipaka (cooked in a pot):
A person who cooks animals and birds is cooked alive in boiling oil by Yamadutas here, for as many years as there were hairs on the bodies of their animal victims.
Kalasutra (thread of Time/Death):
The Bhagavata Purana assigns this hell to a murderer of a brahmin (the Hindu priestly caste), while the Devi Bhagavata Purana allocates it for a person who disrespects his parents, elders, ancestors or brahmins. This realm is made entirely of copper and extremely hot, heated by fire from below and the red hot sun from above. Here, the sinner burns from within by hunger and thirst and the smouldering heat outside, whether he sleeps, sits, stands or runs.
Asipatravana/Asipatrakanana (forest of sword leaves):
The Bhagavata Purana and the Devi Bhagavata Purana reserve this hell for a person who digresses from the religious teachings of the Vedas and indulges in heresy. The Vishnu Purana states that wanton tree-felling leads to this hell . Yamadutas beat them with whips as they try to run away in the forest where palm trees have swords as leaves. Afflicted with injury of whips and swords, they faint and cry out for help in vain.
Shukaramukha (hog's mouth):
It houses kings or government officials who punish the innocent or grant corporal punishment to a Brahmin. Yamadutas crush him as sugar cane is crushed to extract juice. He will yell and scream in agony, just as the guiltless suffered.
Andhakupa (well with its mouth hidden):
It is the hell where a person who harms others with the intention of malice and harms insects is confined. He is attacked by birds, animals, reptiles, mosquitoes, lice, worms, flies and others, who deprive him of rest and compel him to run hither and thither.
As per the Bhagavata Purana and the Devi Bhagavata Purana, it is where a person who does not share his food with guests, elders, children or the gods, and selfishly eats it alone, and he who eats without performing the five yajnas (panchayajna) is chastised. The Vishnu Purana states that one who loathes his father, Brahmins or the gods and who destroys jewels is punished here. This hell is a 100,000 yojana lake filled with worms. The sinful person is reduced to a worm, who feeds on other worms, which in turn devour his body for 100,000 years.
Sandansa/Sandamsa (hell of pincers):
The Bhagavata Purana and the Devi Bhagavata Purana state that a person who robs a Brahmin or steals jewels or gold from someone, when not in dire need, is confined to this hell. However, the Vishnu Purana tells the violators of vows or rules endure pain here. His body is torn by red-hot iron balls and tongs.
Taptasurmi/Taptamurti (red-hot iron statue):
A man or woman who indulges in illicit sexual relations with a woman or man is beaten by whips and forced to embrace red-hot iron figurines of the opposite sex.
Vajrakantaka-salmali (the silk-cotton tree with thorns like thunderbolts/vajras):
A person who has sexual intercourse with animals or who has excessive coitus is tied to the Vajrakantaka-salmali tree and pulled by Yamadutas so that the thorns tear his body.
Vaitarni/Vaitarna (to be crossed):
It is a river that is believed to lie between Naraka and the earth. This river, which forms the boundary of Naraka, is filled with excreta, urine, pus, blood, hair, nails, bones, marrow, flesh and fat, where fierce aquatic beings eat the person's flesh. As per the Bhagavata Purana and the Devi Bhagavata Purana, a person born in a respectable family – kshatriya (warrior-caste), royal family or government official – who neglects his duty is thrown into this river of hell.The Vishnu Purana assigns it to the destroyer of a bee-hive or a town.
Puyoda (water of pus):
Shudras (workmen-caste) and husbands or sexual partners of lowly women and prostitutes – who live like animals devoid of cleanliness and good behaviour – fall in Puyoda, the ocean of pus, excreta, urine, mucus, saliva and other repugnant things. Here, they are forced to eat these disgusting things.
Pranarodha (obstruction to life):
Some Brahmins, Kshatriyas and Vaishyas (merchant caste) indulge in the sport of hunting with their dogs and donkeys in the forest, resulting in wanton killing of animals. Yamadutas play archery sport with them as the targets in this hell.
The Bhagavata Purana and the Devi Bhagavata Purana mention that Yamadutas whip a person, who has pride of his rank and wealth and sacrifices animals as a status symbol, and finally kill him. The Vishnu Puranaassociates it with the maker of spears, swords, and other weapons.
Lalabhaksa (saliva as food):
As per the Bhagavata Purana and the Devi Bhagavata Purana, a Brahmin, a Ksahtriya or a Vaishya husband, who forces his wife to drink his semen out of lust and to enforce his control, is thrown in a river of semen, which he is forced to drink. The Vishnu Purana disagrees stating that one who eats before offering food to the gods, the ancestors or guests is brought to this hell.
Sarameyadana (hell of the sons of Sarama):
Plunderers who burn houses and poison people for wealth, and kings and other government officials, who grab money of merchants, mass murder or ruin the nation, are cast into this hell. Seven hundred and twenty ferocious dogs, the sons of Sarama, with razor-sharp teeth, prey on them at the behest of Yamadutas.
Avici/Avicimat (waterless/wave less):
A person, who lies on oath or in business, is repeatedly thrown head-first from a 100 yojana high mountain whose sides are stone waves, but without water. His body is continuously broken, but it is made sure that he does not die.
Anybody else under oath or a Brahmin who drinks alcohol is punished here. Yamadutas stand on their chests and force them to drink molten-iron.
Ksarakardama (acidic/saline mud/filth):
One who in false pride, does not honour a person higher than him by birth, austerity, knowledge, behaviour, caste or spiritual order, is tortured in this hell. Yamadutas throw him head-first and torment him.
Raksogana-bhojana (food of Rakshasas):
Those who practise human-sacrifice and cannibalism are condemned to this hell. Their victims, in the form of Rakshasas, cut them with sharp knives and swords. The Rakshasas feast on their blood and sing and dance in joy, just as the sinners slaughtered their victims.
Shulaprota (pierced by sharp pointed spear/dart):
Some people give shelter to birds or animals pretending to be their saviours, but then harass them poking with threads, needles or using them like lifeless toys. Also, some people behave the same way to humans, winning their confidence and then killing them with sharp tridents or lances. The bodies of such sinners, fatigued with hunger and thirst, are pierced with sharp, needle-like spears. Ferocious carnivorous birds like vultures and herons tear and gorge their flesh.
Filled with envy and fury, some people harm others like snakes. These are destined to be devoured by five or seven hooded serpents in this hell.
Avata-nirodhana (confined in a hole):
People who imprison others in dark wells, crannies or mountain caves are pushed into this hell, a dark well engulfed with poisonous fumes and smoke that suffocates them.
A householder who welcomes guests with cruel glances and abuses them is restrained in this hell. Hard-eyed vultures, herons, crows and similar birds gaze on them and suddenly fly and pluck his eyes.
An ever-suspicious man is always wary of people trying to grab his wealth. Proud of his money, he sins to gain and to retain it. Yamadutas stitch thread through his whole body in this hell.
The Sinners according to their sins are sent to various naraka's and for the time as per their sins.
