 The only source of information that exists today about this philosopher is the form of "purvapaksa"—a material available in the works of others, which are cited for refutation.The Buddhist "Payasisuttanta" and the Jain Agama "Rayapasenaijja" (Sanskrit "Rājapraśnīya") both were devoted to the refutation of Payasi's views.They both claim that he eventually converted to Buddhism or Jainism.
