Adhyāya 31: Rājasūya-samāgama — The Gathering of Kings and the Ordering of Hospitality
सुकुमारं वशे चक्रे सुमित्रं च नराधिपम् । तथैवापरमत्स्यांश्ष व्यजयत् स पटच्चरान्
sukumāraṁ vaśe cakre sumitraṁ ca narādhipam | tathaivāparamatsyāṁś ca vyajayat sa paṭaccarān |
Vaiśampāyana said: He brought King Sukumāra under his control, and likewise King Sumitra. In the same way he subdued the remaining Matsya chiefs and defeated the marauding bandits.
वैशम्पायन उवाच
The verse underscores a kingly duty (rājadharma): establishing order by bringing rival rulers into lawful submission and suppressing banditry. Legitimate force is portrayed as serving stability and protection, contrasting with predatory violence.
In the account narrated by Vaiśampāyana, the conquering leader subdues King Sukumāra and King Sumitra, then defeats remaining Matsya leaders and roaming marauders, as part of a wider campaign of regional subjugation.
