Shloka 51

महता रथवंशेन सर्वतः प्रत्यवारयन्‌ । तत्पश्चात्‌ कौरव-सेनाके सभी श्रेष्ठ महारथियोंने विशाल रथसमूहके द्वारा कृपाचार्यको सब ओरसे घेर लिया ।। ५० ई || विस्फारयन्तश्नापानि विसृजन्तश्न सायकान्‌

sañjaya uvāca | mahatā rathavaṁśena sarvataḥ pratyavārayan | tatpaścāt kaurava-senāyāḥ sarve śreṣṭhā mahārathino viśālena rathasaṁghena kṛpācāryaṁ samantataḥ paryavārayan | visphārayantaś cāpāni visṛjantaś ca sāyakān |

Sanjaya said: With a vast mass of chariots they checked him from every side. Thereafter, the foremost great chariot-warriors of the Kaurava host, forming a broad chariot-formation, surrounded Kripa, the preceptor, on all sides—twanging their bows and releasing volleys of arrows. The scene underscores how, in the press of war, even revered teachers become tactical centers to be protected or enclosed, and how collective force can override individual prowess.

Educational Q&A

The verse highlights the ethical tension of warfare: reverence for a teacher (ācārya) persists, yet battlefield necessity turns even venerable figures into strategic focal points. It also illustrates how coordinated collective action (formations, encirclement) can restrain or protect against individual martial power.

Sanjaya describes a moment where a large chariot contingent checks movement on all sides, and the leading Kaurava warriors form a broad chariot-group to surround Kripacharya, while bowstrings thunder and arrows are shot in volleys.
