AITAREYA UPANISHAD · 2.1.5

तदुक्तमृषिणा — गर्भे नु सन्नन्वेषामवेदमहं देवानां जनिमानि विश्वा । शतं मा पुर आयसीररक्षन्नधः श्येनो जवसा निरदीयमिति । गर्भ एवैतच्छयानो वामदेव एवमुवाच ॥ ५ ॥

taduktamṛṣiṇā — garbhe nu sannanveṣāmavedamahaṃ devānāṃ janimāni viśvā । śataṃ mā pura āyasīrarakṣannadhaḥ śyeno javasā niradīyamiti । garbha evaitacchayāno vāmadeva evamuvāca ॥ 5 ॥

Therefore it was said by the sage Vamadeva: “I, Vamadeva, being yet in the womb, knew all the births of these gods and their causes. In a hundred cities of iron they held me down and kept me; I broke through them all with might & violence, like a hawk I soared up into my heavens.” While yet he lay in the womb, thus said Vamadeva.
