त्रयी चान्वीक्षिकी चैव वार्ता च भरतर्षभ । दण्डनीतिश्न विपुला विद्यास्तत्र निदर्शिता:,भरतश्रेष्ठ! उस ग्रन्थमें वेदत्रयी (कर्मकाण्ड), आन्वीक्षिकी (ज्ञानकाण्ड), वार्ता (कृषि, गोरक्षा और वाणिज्य) और दण्डनीति--इन विपुल विद्याओंका निरूपण किया गया है
trayī cānvīkṣikī caiva vārtā ca bharatarṣabha | daṇḍanītiś ca vipulā vidyās tatra nidarśitāḥ ||
Bhīṣma said: “O bull among the Bharatas, in that treatise are set forth these extensive branches of learning—the three Vedas, rational inquiry (philosophical investigation), practical economics (agriculture, cattle-rearing, and trade), and the science of governance and punishment (statecraft).”

Bhīṣma identifies the major disciplines a ruler (and society) should know: sacred learning (trayī), critical inquiry (ānvīkṣikī), material prosperity through productive economy (vārtā), and governance through law and policy (daṇḍanīti). Together they balance spiritual authority, rational discernment, wealth-creation, and just administration.
In Śānti Parva, Bhīṣma instructs the Bharata prince on dharma and governance. Here he points to a referenced treatise/teaching in which these broad sciences are systematically explained, emphasizing the intellectual foundations of righteous rule.
