Daṇḍotpatti-kathana (Origin and Function of Daṇḍa) — वसुहोम–मान्धातृ संवाद
यथोक्तमेतद् वचन प्रागेव मनुना पुरा । यन्मयोक्तं मनुष्येन्द्र ब्रह्मणो वचन महत्
bhīṣma uvāca | yathoktam etad vacanaṃ prāg eva manunā purā | yan mayoktaṃ manuṣyendra brahmaṇo vacanaṃ mahat ||
Bhishma said: “This very statement was indeed spoken long ago by Manu. O best of men, what I have declared is the great utterance of Brahmā. Since Manu had already proclaimed it earlier, it is also known as the ‘former utterance’ (prāg-vacana). And because it lays down the principles of practical conduct and adjudication, it is here designated as ‘vyavahāra’ (rules of worldly/legal procedure).”
भीष्म उवाच
Bhishma grounds his instruction in recognized authority: the same rule was taught earlier by Manu and ultimately reflects Brahmā’s great pronouncement. Because it guides practical dealings and adjudication, it is classified under vyavahāra—dharma as applied to real-world conduct and legal order.
In the Śānti Parva dialogue, Bhishma continues advising the king (Yudhiṣṭhira). Here he clarifies that his present teaching is not novel: it is an ancient doctrine already stated by Manu and traceable to Brahmā, thereby reinforcing its legitimacy for governance and social/legal practice.
