This book presents Tantrayukti, a classical Indian science of structured reasoning, textual analysis, and knowledge presentation, as a practical tool for modern research and academic writing across disciplines. Prof. M. Jayaraman explains how these ancient techniques sharpen thinking, help organize arguments, enhance coherence, and improve the clarity of thesis construction and scholarly communication.Through illustrations and comparative insights from Sanskrit and ancient Tamil texts, the book demonstrates how Tantrayukti trains the mind to read deeply, reason precisely, and present knowledge systematically. It offers clear explanations of the yuktis supported by examples, charts, appendices, and extensive references, making it valuable not only for those engaged with Indian knowledge but for any researcher, teacher, or student seeking stronger methodological foundations."A welcome addition to research methodology, offering robust approaches rooted in India's knowledge traditions."Dr B Mahadevan, IIM Bangalore"It brings Eastern cognitive wisdom and Western academic rigor together, laying a strong foundation for holistic research."Padmashri Dr H R Nagendra, President, SVYASA SocietyBy bridging ancient cognitive tools with modern academic needs, this book invites readers to rethink how knowledge is analyzed, structured, and communicated.
