Bhashya
राजन्या बन्धवो यस्येति ; परिभववचनमेतत् राजन्यबन्धु-रिति ; अप्राक्षीन् पृष्टवान् ; ततः तस्मात् न एकंचन एकमपिन वेद न विज्ञातवानस्मि ।कतमे ते राज्ञा पृष्टाः प्रश्ना इतिपित्रा उक्तः पुत्रः ‘इमे ते’ इति ह प्रतीकानि मुखानिप्रश्नानाम् उदाजहार उदाहृतवान् ॥
In plain words
'One whose kinsmen are warriors' — that's a jab, a put-down: 'you kshatriya's kinsman.' The king had questioned him, and that's exactly why: I don't know even one, I never understood a single one. 'Which questions did the king ask you?' his father demanded. So addressed, the son recited the opening lines of each question — 'here they are,' he said, laying them out one by one.
Close to the Sanskrit
'One whose kinsmen are kshatriyas' — this is an expression of contempt: 'you kshatriya's-kinsman.' He had asked him a question; therefore I do not know even one — I have not understood it. 'Which were the questions asked by the king?' Thus addressed by the father, the son recited the opening phrases of the questions, saying 'these are they' — udājahāra means 'he stated them aloud.'
