Purport
After realizing none other than God is in front of him, Arjuna got overwhelmed. He accepted it is beyond the capacity for any human, devatas or Danvans to know about Shri Krishna on his own until Shri Krishna himself let himself known.
In earlier Shlokas, Arjuna submitted himself completely in the lotus feet of Shri Krishna. In this Shloka he expresses his desires to know the glories of Shri Krishna and requested Shri Krishna to tell more of those divine glories[Of Shri Krishna].
