Bhagavad Gita 11.47
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.
श्री भगवानुवाच
मया प्रसन्नेन तवार्जुनेदं
रूपं परं दर्शितमात्मयोगात्।
तेजोमयं विश्वमनन्तमाद्यं
यन्मे त्वदन्येन न दृष्टपूर्वम्॥śrī bhagavānuvāca
mayā prasannena tavārjunedaṃ
rūpaṃ paraṃ darśitamātmayogāt|
tejomayaṃ viśvamanantamādyaṃ
yanme tvadanyena na dṛṣṭapūrvam||
