Shloka 21
नकुलो मूषिकानत्ति बिडालो नकुलं तथा | बिडालमत्ति श्वा राजन् श्वानं व्यालमृगस्तथा,राजन! नेवला चूहेको खा जाता है और नेवलेको बिलाव। बिलावको कुत्ता और कुत्तेको चीता चबा जाता है
nakulo mūṣikān atti biḍālo nakulaṃ tathā | biḍālam atti śvā rājan śvānaṃ vyāla-mṛgas tathā ||
अर्जुन उवाच—नकुलो मूषिकानत्ति, बिडालो नकुलं तथा। बिडालमत्ति श्वा राजन्, श्वानं व्यालमृगस्तथा॥
अजुन उवाच
