[4] The 12th century Jain scholar Hemachandra mentions a legend according to which Karna prayed to the goddess Lakshmi for a son.

He restored a temple of Lakshmi, and meditated for a long time, overcoming seductive apsaras and a threatening demon.

As Hemachandra was a courtier of both Jayasimha and Kumarapala, historian A. K. Majumdar theorizes that he created a fictional account to hide an unpleasant truth.

[6] Multiple literary sources as well as inscriptions establish that Jayasimha defeated Khangara alias Navaghana, the king of Saurashtra.

[8] Jain chronicler Prabhachandra mentions that Siddharaja had first dispatched an army led by Kirtipala (brother of Kumarapala) to attack Navaghana.

The later 1262 CE Sundha Hill inscription also states that Asharaja pleased Jayasimha by helping him in a campaign in Malwa.

Arnoraja's ancestor Vigraharaja III had helped the Paramara king Udayaditya against Jayasimha's father Karna.

[11] The Chaulukya poet Someshvara, in his Kirti-Kaumudi, states that when Arnoraja saw the severed heads of kings lying before his feet, he bowed to Jayasimha out of fear.

[12] An inscription discovered at the Chahamana capital Shakambhari (modern Sambhar) provides a genealogy of the Chaulukya kings, from Mularaja to Jayasimha.

[14] Jayasimha Suri claims that when Siddharaja decided to invade the Paramara kingdom, he took a vow to make a scabbard for his sword with Naravarman's skin.

When the emissary reminded him about the fate of the Paramaras, he derisively asked his minister to make Jayasimha return by paying him some money.

The Permardi mentioned in the Talwara inscription is unlikely to be Vikramaditya VI, since such a victory would have been the greatest military success of Jayasimha.

Historian A. K. Majumdar identifies him with Perma-nripa, the son of an obscure king named Pitta, mentioned in a Huli inscription.

[23] The Kalyani Chalukya records claim that Vikramaditya VI crossed the Narmada river, and conquered the Lata and Gurjara regions.

According to Hemachandra, Barbaraka was a rakshasa (demon), who harassed the sages of the hermitage located on the banks of the Sarasvati River at Shristhala (Siddhapura).

The historical identification of Barbaraka is not certain, but scholars such as Georg Bühler and Bhagwan Lal Indraji speculated that he was a non-Aryan tribal chief.

Historian A. K. Majumdar speculates that Jayachandra may have assisted his grandfather in an expedition; Merutunga's claim probably refers to an alliance between the Chaulukyas and the Gahadavalas.

This is corroborated by the chronicler Somaprabha who mentions that Jayasimha considered Sripala his brother, and bestowed the title of Kavindra upon him.

Someshvara states that Kumara's blessings helped Jayasimha subjugate the rulers of Sindhu-desha, Malava, and Sapadalaksha.

[39] The king's religious perceptor was Bhava Brihaspati, who originally lived in Malwa, and had been brought to Gujarat after Jayasimha's victory over the Paramaras.

A stepwell in Nadiad and Minaldevi Vav in Virpur in Rajkot district are also ascribed to her and has stylistic affinities to Chaulukya architecture.

[46] According to Hemachandra's Dvyashrya-Kavya, Jayasimha made arrangements for the maintenance of Jain monks, and also visited the shrine of Neminatha on his way to Somanatha.

[26] Some later Jain chronicles claim that Hemachandra convinced Jayasimha that Jainism was superior to Shaivism, and that the king banned animal slaughter for 8 days in each year.

The 14th century chronicler Merutunga states that Jayasimha once banned the Jain temples from hoisting their banners, but later revoked it, acknowledging it as a mistake.

His minister and later governor of Sorath, Sajjana built Neminath temple on Mount Girnar which was consecrated in 1129 CE according to Jinaprabha and other sources.

The Dahod inscription mentions Goga Narayan temple built by Senapati Keshava in memory of his mother in 1140 CE.

[41] Jayasimha extended his religious tolerance to Islam as well, and the Muslim historian Muhammad Aufi has recorded stories about his impartiality.

Siddharaja declared it was his duty as king to let his subjects live in peace and practice their religion, and paid 1 lakh of Balotras to rebuild the mosque.

[48][49][50] According to a legend, a da'i named Ahmad once took two Gujarati orphans (Abdullah and Nuruddin) to Cairo, trained them in the Ismaili doctrine, and sent them back to Gujarat as missionary.

There is no evidence that Jayasimha ever gave up Shaivism, but several of the Bohra Walis and Da'i al-Mutlaqs claimed descent from him.
