Akbar's court, mentions a symposium of philosophers of all faiths held in 1578 at Akbar's instance. The account is given by the historian Vincent Smith, in his article titled "The Jain Teachers of Akbar". Some Carvaka thinkers are said to have participated in the symposium. Under the heading "Nastika" Abul Fazl has referred to the good work, judicious administration and welfare schemes that were emphasised by the Charvaka law-makers. Somadeva has also mentioned the Charvaka method of defeating the enemies of the nation. Mention in Mahabharata In the epic Mahabharata, Book 12 Chapter 39, a rakshasa dresses up like a Brahmin and appoints himself as spokesperson for all Brahmins is named Charvaka. Charvaka criticizes Yudhishthira for killing his kinsmen, superiors, and teacher, and claims that all the Brahmins are uttering maledictions to him. Yudhishthira is ashamed of this, but the Brahmin Vaishampayana reassures him. The Brahmins, now filled with rage, destroy Charvaka with the power of their mantras. Mention in other works No independent works on Charvaka philosophy can be found except for a few sūtras attributed to Brihaspati. The 8th century Tattvopaplavasimha of Jayarāśi Bhaṭṭa with Madhyamaka influence is a significant source of Charvaka philosophy. Shatdarshan Samuchay and Sarvadarśanasaṅ̇graha of Vidyaranya are a few other works which elucidate Charvaka thought. One of the widely studied references to the Charvaka philosophy is the Sarva-darśana-saṅgraha (etymologically all-philosophy-collection), a famous work of 14th century Advaita Vedanta philosopher Mādhava Vidyāraṇya from South India, which starts with a chapter on the Charvaka system. After invoking, in the Prologue of the book, the Hindu gods Shiva and Vishnu ("by whom the earth and rest were produced"), Vidyāraṇya asks, in the first chapter: Sanskrit poems and plays like the Naiṣadha-carita, Prabodha-candrodaya, Āgama-dambara, Vidvanmoda-taraṅgiṇī and Kādambarī contain representations of the Charvaka thought. However, the authors of these works were thoroughly opposed to materialism and tried to portray the Charvaka in an unfavourable light. Therefore, their works should only be accepted critically. Loss of original works There was no continuity in the Charvaka tradition after the 12th century. Whatever is written on Charvaka post this is based on second-hand knowledge, learned from preceptors to disciples and no independent works on Charvaka philosophy can be found. Chatterjee and Datta explain that our understanding of Charvaka philosophy is fragmentary, based largely on criticism of its ideas by other schools, and that it is not a living tradition: "Though materialism in
