Historian Asoke Majumdar theorizes that Mularaja attacked Graharipu on "some flimsy pretext", as Mahadeva's-order-in-a-dream was a popular device used by Sanskrit authors to justify the otherwise inexcusable actions of their heroes. Mularaja's descendants fought against the kings of Kachchha and Saurashtra, so it appears that he managed to annex some parts of these kingdoms, but could not completely subjugate them. Merutunga states that Mularaja once faced simultaneous invasions at the northern and southern frontiers of his kingdom. The northern invader was the king of Sapadalaksha, who can be identified as the Shakambhari Chahamana ruler Vigraharaja II. This invasion finds a mention in the later Chahamana accounts, but is not mentioned in Vigraharaja's 973 CE inscription, so it must have happened sometime after 973 CE. The southern invader was the Lata Chalukya ruler Barapa, a vassal of the Kalyani Chalukya ruler Tailapa II. According to Merutunga, Mularaja's ministers advised him to take shelter in the Kantha-durga fort until Navaratri, when Vigraharaja would depart to perform the traditional worship of his family deity, and then attack Barapa. Mularaja agreed to this suggestion, but unexpectedly, Vigraharaja did not depart on Navaratri. Mularaja then collected a large number of soldiers from different parts of his kingdom, and led an army to the Chahamana camp. He managed to enter the royal pavallion of Vigraharaja, who, after a short conversation, was impressed with his bravery. Mularaja asked Vigraharaja not to attack him while he was engaged in a war with Barapa, and the Chahamana agreed to the demand. Vigraharaja also promised to maintain friendly relations with Mularaja, who subsequently attacked and killed Barapa. "Prithviraja Vijaya", which was composed under Chahamana patronage, states that Vigraharaja forced Mularaja to take shelter in Kantha-durga, and advanced as far as Bhrigukachchha (modern Bharuch), where he built a temple dedicated to the goddess Ashapuri. The 15th century "Hammira Mahakavya", which glorifies the Chahamana lineage, inaccurate claims that Vigraharaja killed Mularaja.
