saṃjaya uvāca |
ityuktvā vyathito rājā novāca gatacetanaḥ |
taṃ gautamaḥ pratyuvāca vijñāyāsya vivakṣitam |
avadhyo'haṃ mahīpāla yudhyasva jayamāpnuhi || 69 ||

"Yudhishthira said, 'Alas, I ask thee, therefore., O preceptor, listen to my words.--Saying this, the king, greatly agitated and deprived of his sense, stood silent."

Sanjaya continued.--"Understanding, however, what he intended to say, Gautama (Kripa) replied to him, saying,--I am incapable of being slain, O king. Fight, and obtain victory. I am gratified with thy coming. Rising every day [from bed] I will pray for thy victory, O monarch. I say this to thee truly.--Hearing, O king, these words of Gautama, and paying him due honours, the king proceeded thither where the ruler of the Madra was. Saluting Salya and walking round him the king said unto that invincible warrior those words that were for his own benefit.
