Jalandhara
Jalandhara (Sanskrit: जलन्धर, lit. "he who holds water"), also known as Chalantarana (Sanskrit: चलन्तरण, lit. "he who walks and swims") was an evil demigod. He was born when Shiva opened his third eye to destroy Indra for his arrogance. However, Indra was saved and the energy emitted from the eye was sent into ocean. The energy developed into a boy and was raised by Varuna and later, Shukracharya (Guru of Asuras). When he grew up, he conquered the three realms - Swarga (heaven), Bhuloka (earth) and Patala (hell). He married Vrinda, a pious lady. Later, Shiva slew him for his  evil deeds. Birth. In the Shiva Purana, when Indra and Brihaspati were going towards Mount Kailash to meet Shiva their way was blocked by a yogi with matted hair and a radiant face. The yogi was Shiva himself, who had taken the form to test the knowledge of Indra and Brihaspati. Indra did not recognize the yogi and was infuriated at the fact that the man was not moving out of their way. Indra asked him to move but the man did not budge. After not getting any reply Indra became enraged and threatened him with his thunderbolt. Upon this  action Indra's arm became paralyzed and Shiva neutralized the thunderbolt. Shiva became angry upon this action of Indra and his eyes turned red, frightening Indra. The anger caused Third eye to open, nearly killing Indra. Brihaspati recognized Shiva and prayed to him, requesting him to pardon Indra. To avoid killing Indra, Shiva sent the fire from his eye towards the ocean and upon meeting with the ocean it assumed the form of a boy. The boy cried terribly which caused Brahma to descend from his abode. The ocean told Brahma that he did not know where the boy came  from. Brahma then told him that the boy will one day become the emperor of Asuras, he could only be killed by Shiva and after his death he would return to Third eye. Jalandhara, the emperor of the three realms. Jalandhara's childhood was full of wonders. Borne up by the wind, he flew over the ocean; his pets were lions which he had caught; and the largest birds and fishes were subject to him. Jalandhara grew up to be a handsome man and was made the emperor of Asuras by Shukra, their guru. Jalandhara was exceedingly powerful and is  considered to be one of the mightiest asuras of all time. He married Vrinda, the daughter of the Asura Kalanemi. Jalandhara ruled with justice and nobility. One day sage Bhrigu came to meet Jalandhara. He narrated the tales of Hiranyakashipu and Virochana. He also tells him how Vishnu severed Rahu's head and about the Samudra manthan. Jalandhara resented the Samudra manthan. He believed that the Devas had treacherously taken his father, Varuna's treasures. He sent one of his messengers, Ghasmar, to Indra to ask him to return his father's treasures. However Indra refused to do so. A  fierce battle took place between the Devas and Asuras. Many warriors were killed on both sides. Shukra revived the Asuras using his Mritsanjivani vidya. Brihaspati revived the dead Devas by using the medicinal herbs from the Drongiri mountain. Shukra ordered Jalandhara to submerge the mountain so Brihaspati cannot use the medicinal herbs to revive the Devas. Jalandhara obeyed the command and submerged Drongiri mountain. Demoralized, the Devas requested Vishnu for his aid. Vishnu agreed but promised Lakshmi that he would not kill Jalandhara since he was born out of the ocean and Lakshmi considered him as her brother. A  fierce battle was fought between Jalandhara during which Lord Vishnu overpowered Jalandhar and was about to behead Jalandhar with his divine sword, Nandak when Lakshmi intervened and prohibited Lord Vishnu from killing him. Vishnu was impressed by Jalandhara's valiance in battle and told him about Lakshmi's relationship with him. Vishnu then asked him to demand any boon he desired. Jalandhara asked Vishnu to make Ksheera Sagara his home. He agreed and started living there along with Lakshmi. Without his help the Devas were defeated by Asuras and Jalandhara became the emperor of the three worlds (heaven, earth and  hell). Conflicts with Shiva. The Devas were unhappy about their defeat. They did not wish to be ruled by Jalandhara despite the fact that he was the creation of Shiva. The sage Narada upon consulting with the Devas went to see Jalandhara. On being asked the purpose of his visit by Jalandhara he described the beauty of Kailash where Shiva lived and that he wondered whether any other place matched its beauty. In response, Jalandhara showed off his riches to Narada who commented that he did not have the most beautiful woman as his wife. Narada then continued to describe  Shiva's residence and also described to him about Parvati's beauty. Jalandhara sends his messenger Rahu to Shiva and accuses him of hypocrisy, pointing out that Shiva claims to be an ascetic but keeps a wife, Parvati. He proposes that Shiva hand over Parvati to him: How can you live on alms and yet keep the beautiful Parvati? Give her to me, and wander from house to house with your alms bowl. You have fallen from your vow. You are a yogi, what need have you for the gem of wives? You live in the woods attended by goblins  and ghosts; being a naked yogi, you should give your wife to one who will appreciate her better than you do. Upon hearing these insults, Shiva became so angry that a fearsome creature (Kīrttimukha) sprang from his brow and nearly killed Rahu, the messenger who had delivered the demand. War being determined on, Jalandhara marched first to Kailash; but finding that Shiva had forsaken it and taken up a position on a mountain near Lake Manasa, he surrounded the mountain with his troops. Nandi marched against them, and spread destruction; however, the army of the gods suffered many losses. Parvati  then urged Shiva to enter the war. Shiva carefully warned Parvati to be on her guard during his absence, as it was possible asuras in some disguise might visit her; after this, accompanied by Virabhadra and Manibhadra, two forms of his anger, Shiva went to the battlefield. Kartikeya came to fight with him, but was defeated. After his defeat, Ganesha tried to dominate over him, but was badly defeated by him and was left unconscious on the battlefield. Upon seeing Shiva and his avatars dominate the battlefield, Jalandhara created an illusion of beautiful apsaras singing and dancing. This distracted his  army but not himself. Meanwhile, Jalandhara disguised himself as Shiva and went to Parvati in order to trick her. Parvati recognized him and became very angry. Puranas states that on recognizing this deception, Parvati was so enraged that her eyes turned blood red and her face, pitch black indicating her assumption of her form of Kali. She attempted to attack him but Jalandhara escaped knowing he was no match for the Goddess's anger. Parvati then went to Vishnu and requested him to trick Vrinda just like Jalandhara tried to trick her. Jalandhara's wife Vrinda was very pious. First , Vishnu created an illusion that Jalandhara had been killed by Shiva and is then restored to life by him. Vrinda then embraces Jalandhara who is actually Vishnu in disguise. Vrinda realizes that it is Vishnu in disguise and curses him that someday someone would trick his own wife (which becomes true when Sita is kidnapped by Ravana) just like how he had tricked her as a result of which the world will raise a finger on his wife's purity and he would be helpless against the onslaught, for having ruined her chastity. She adds that he will bear the  pain of separation from his wife, similar to her husband. She also admonishes him for being stone-hearted and curses that one day he will turn to stone itself. Saying so, she enters the fire to immolate herself. Vishnu, himself being the overseer of all the boons and curses, accepts Vrinda's curse. Moreover, he blesses her that she would be worshipped as a goddess and her involvement will be must for Vishnu's worship. The curses come true aeons later when Sita gets kidnapped by Ravana, consequently, she is to give the test of purity by fire. Regardless, she  is sent into exile once again, where she raises twins, Luv and Kusha. After entrusting their care to Rama, Sita beckons her mother, Bhūmi to grant her solace and release from a life of unhappiness, as testament to her purity, chastity and innocence, leaving Rama heartbroken. Death. Jalandhara, hearing of this deception and his wife's death, was mad with rage and left Mount Kailash, and returned to the battlefield. The illusion by this time had ended and Shiva's army realized the truth. No illusion can be cast on Shiva. Shiva engaged Sumbha and Nisumbha in battle but they  fled. They were later killed by Parvati. Jalandhara then engaged Shiva in battle. Towards the end of the battle when most of Jalandhara's army was slaughtered, Shiva himself took the form of Panchanana Mahadev, that is the one with 5 heads and killed Jalandhara by thrusting his Trishula into his chest and cutting his head off with a chakra (discus) created from his toe. Upon his death his soul merged with Lord Shiva just like Vrinda's soul had merged with Lord Vishnu.
