"These few points, plus some details on Prithviraj’s ancestors, are the main political facts to be gleaned from Prthvīrāja Vijaya, but the text is more interesting and informative when it comes to cultural attitudes towards the Muslim enemies of the Chahamanas. We have already seen that it describes Shihab al-Din as a wicked eater of cows, portrays his ambassador as alien in appearance to the point of extreme ugliness, and castigates the “Goris” for their destructive nature. At the outset of the poem, Brahma makes a plea to Vishnu to be born on earth in order to rectify the Muslim desecration of Pushkar, the holy site dedicated to Brahma that is near Ajmer – the answer to his prayer is our hero Prithviraj, frequently identified in the text as a form of Vishnu. Subsequently, we are told that King Arnoraja had a lake created in order to cleanse the earth of impurity from the many Muslim deaths that occurred during the course of an assault on the Chahamana capital. The Chahamana kings are hence firmly placed on the side of the gods, fighting against the forces of evil, in these flattering scenarios."
