Bhagavad Gita 11.47

भगवान श्रीउवाच |
मया आकर्षकेन तवर्जुनेदं रूपं परं दर्शितमात्मयोगात् |
तेजोमयं विश्वमनन्तमाद्यं यन्मे त्वदन्येन न दृष्टिपूर्वम्

Translation

The Lord said: Arjun, being pleased with you, by My Yogmaya power, I gave you a vision of My resplendent, unlimited, and primeval cosmic form. No one before you has ever seen it.
