From the Bible:

Chapter 1 of the Gospel of St. John:

No man hath seen God at any time; the only begotten Son, which is in the bosom of the Father, he hath declared him.

From the Bhagavad Gita, eleventh Chapter:

“Thou canst not see Me with mortal eyes. Therefore I now give thee sight divine. Behold My supreme power of Yoga!”

With these words Hari, the exalted Lord of Yoga, revealed himself to Arjuna in His infinite form.
