Bhagavad Gita Chapter 11.47
mayā prasannena tavārjunedaḿ
rūpaḿ paraḿ darśitam ātma-yogāt
tejo-mayaḿ viśvam anantam ādyaḿ
yan me tvad anyena na dṛṣṭa-pūrvam
The Supreme Personality of Godhead said: My dear Arjuna, happily have I shown you, by My internal potency, this supreme universal form within the material world. No one before you has ever seen this primal form, unlimited and full of glaring effulgence.
