Bhagavad Gita 11.47
श्री भगवानुवाच · śrī bhagavānuvāca
मया प्रसन्नेन तवार्जुनेदंरूपं परं दर्शितमात्मयोगात्।तेजोमयं विश्वमनन्तमाद्यंयन्मे त्वदन्येन न दृष्टपूर्वम्॥
mayā prasannena tavārjunedaṃrūpaṃ paraṃ darśitamātmayogāt |tejomayaṃ viśvamanantamādyaṃyanme tvadanyena na dṛṣṭapūrvam ||
The Blessed Lord said, "O Arjuna, this Cosmic Form has graciously been shown to you by Me through My own Yogic power. It is full of splendour, primeval, and infinite; this Cosmic Form of Mine has never been seen before by anyone other than you."
Lord Shri Krishna replied: My beloved friend! It is only through My grace and power that you have been able to see this vision of splendour, the Universal, the Infinite, the Original. Never has it been seen by anyone else.
