Jalandhar was one of the greatest warriors ever mentioned in ancient hindu texts. As per Shiv Puran, Jalandhar was the only warrior who defeated both Lord Ganesh and Kartikey single handedly.
As per Shiv Puran, when Indra and Brihaspati were going towards Mount Kailash to meet Shiv their way was blocked by a yogi with matted hair and a radiant face. The yogi was Shiv himself, who had taken the form to test the knowledge of Indra and Brihaspati. Indra did not recognize the yogi. He asked him to move but the man did not budge. After getting no reply Indra became enraged and threatened him with his thunderbolt.
BIRTH OF JALANDHAR
Upon this action Indra's arm became paralyzed and Shiv neutralized the thunderbolt. Shiv became angry upon this action of Indra and his eyes turned red, frightening Indra. The anger caused Shiv's third eye to open, nearly killing Indra. Brihaspati recognized Shiv and prayed to him, requesting him to pardon Indra.
To avoid killing Indra, Shiv 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 heaven. 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 Shiv and after his death he would return to Shiv's third eye.
JALANDHAR's REVOLT AGAINST DEVTAS
Jalandhar 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. Jalandhar ruled with justice and nobility. One day sage Bhrigu came to meet Jalandhar. He narrated the tales of Hiranyakashipu and Virochana. He also tells him how Vishnu severed Rahu's head and about the Samudra manthan. Jalandhar resented the Samudra manthan. He believed that the Devtas 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 Devtas and Asuras. Devtas severly defeated.
Demoralized, the Devtas requested Vishnu for his aid. Vishnu agreed but promised Lakshmi that he would not kill Jalandhar since he was born out of the ocean and Lakshmi considered him as her brother. A fierce battle was fought between Jalandhar 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 Jalandhar's valiance in battle and told him about Lakshmi's relationship with him. Vishnu then asked him to demand any boon he desired. Jalandhar asked Vishnu to make Ksheera Sagara his home. Vishnu agreed and Jalandhar started living there along with Lakshmi. Very soon, Jalandhar became the emperor of the three worlds (heaven, earth and hell).
JALANDHAR's MARRIAGE PROPOSAL FOR PARVATI
The Devtas were unhappy about their defeat. They did not wish to be ruled by Jalandhar despite the fact that he was the son of Shiv. The sage Narad upon consulting with the Devtas went to see Jalandhar. On being asked the purpose of his visit by Jalandhar he described the beauty of Kailash where Shiv lived and that he wondered whether any other place matched its beauty. In response, Jalandhar showed off his riches to Narad who commented that he did not have the most beautiful woman as his wife. Narad then continued to describe Shiv's residence and also described to him about Parvati's beauty.
Finally, Jalandhar sends his messenger Rahu to Shiv and accuses him of hypocrisy, pointing out that Shiv claims to be an ascetic but keeps a wife, Parvati. He proposes that Shiv should hand over Parvati to him.
Upon hearing these insults Shiv becomes 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, Jalandhar marched first to Kailash; but finding that Shiv had forsaken it and taken up a position on a mountain near Lake Manasa, he surrounded the mountain with his troops. Nandi (bull) marched against them, and spread destruction, however, the army of the gods suffered losses. Parvati then urged Shiv to enter the war. Shiv 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, Shiv went to the battlefield.
WAR BETWEEN JALANDHAR AND SHIV
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 Shiv and his avatars dominate the battlefield, Jalandhar created an illusion of beautiful apsaras singing and dancing. This distracted his army but not himself.
Meanwhile, Jalandhar disguised himself as Shiv 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 Jalandhar escaped knowing he was no match for the goddess's anger.
Parvati then went to Vishnu and requested him to trick Vrinda just like Jalandhar tried to trick her. Jalandhar's wife Vrinda was very pious. First, Vishnu created an illusion that Jalandhar had been killed by Shiv and is then restored to life by him. Vrinda then embraces Jalandhar who is actually Vishnu in disguise. Vrinda realizes that it is Vishnu in disguise and curses him that someday someone would abduct his own wife. This curse shown his effect in Ramayan when Vishnu Avatar Lord Ram’s wife Sita was abducted by Ravan. After cursing Lord Vishnu, Vrinda ends her life by entering into a fire.
Jalandhar, hearing of his wife's deception and death, was mad with rage and left Mount Kailash, and returned to the battlefield. The illusion by this time had ended and Shiv's army realized the truth.
Shiv engaged Sumbha and Nisumbha in battle but they fled. They were later killed by Parvati. Jalandhar then engaged Shiv in battle, who killed him by thrusting his Trishul into his chest and cutting his head off with a chakra created from his toe. Upon his death his soul merged with Shiv just like Vrinda's soul had merged with Lord Vishnu.
