The World in *Purapporul Venbamaalai*

This research paper explores the conceptualization and contextual usage of the term "Ulagam" (The World) in Purapporul Venbamalai, a seminal grammatical work on ancient Tamil heroism and public life. While classical Tamil literature is fundamentally structured around inner emotions (Aham) and external actions (Puram), this study analytically examines how the author, Aiyanarithanar, employs the concept of the world across various poetic themes (Thurai). The research highlights that the term "Ulagam" (and its synonyms like Vaiyagam, Gnyalam, Nalantheevu) transitions through multiple definitions: representing the geopolitical territory protected by a righteous king, identifying the scholarly elite or wise men (Saandror), and serving as a framework for the astronomical predictions of Kaniyan (astrologers). Furthermore, the paper delves into the themes of impermanence (Nilaiyamai), martial martyrdom (Kaiyarunilai), and ethical hospitality (Virundhombal) as depicted in the text. The study concludes that Purapporul Venbamalai utilizes the concept of the world not merely as a geographical entity, but as a socio-ethical compass guiding human conduct, governance, and spiritual detachment.
