Based on the 11th and 12th sarga of Kāśmīrakamahākaviśrījayānakaviracitaṃ Pr̥thvīrājavijayamahākāvyam.
Prithviraja Vijaya Mahakavya was written by Kashmiri poet Jayanaka between 1193-1200 A.D in Ajmer at the royal court of Prithviraj Chauhan III. It was an epic eulogy to the Chauhan, and along with Rajput history, it gives the description of early battles between forces of Prithviraj and Muhammad Ghori.
The only known manuscript of the poem (missing some sections) was found in around 1875 in Kashmir in Sarda script by Georg Bühler. It was a commentary on the work by Jonaraja, who is famous for having written Dvitiya Rajatarangini (second Rajatarangini), covering the period from 1150 A.D. to 1459 A.D.
In 11th sarga, Prithviraj is told the story of destruction of asuras Sunda and Upasunda. He hears about defeat of Ghori's forces in Gujarat. He retires to his picture gallery, browses through his illustrated books and is aroused by image of apsara Tilotamma, the one made from the 'finest bits', the cause of destruction of Sunda and Upasunda. He over hears someone recite a verse, '...everything comes to him who strives to get it.'
In 12 sarga, the reciter is introduced: Jayanaka, from the fine land of Sharda - Kashmira Mandala. A man knowing six languages, great-grandson of a brother of Sivaratha, a minister of King Uchchala of Kashmir (1101-1111 A.D.).
Then the epic abruptly ends.
