BṚHADĀRAṆYAKA UPANISHAD · 6.2.5

स होवाच -- प्रतिज्ञतो म एष वरः ।
यां तु कुमारस्यान्ते वाचम् अभाषथास् तां मे ब्रूहीति ॥

sa hovāca -- pratijñato ma eṣa varaḥ ।
yāṃ tu kumārasyānte vācam abhāṣathās tāṃ me brūhīti ॥

Gautama said: 'That boon is promised to me; tell me the same speech which you made in the presence of my boy.'
