As He promised, He will provide the light of wisdom for you to be enlightened.
Arjuna is in the mood of the perfect devotee and disciple. Anything that he can listen about his Master is nectar to his ears.
He is in a state of complete immersion. Rāmakṛṣṇa asked Vivekananda, 'If you were a fly and you were on the rim of the cup of nectar, what would you do?
Vivekananda said, 'Sip from the cup, of course, what else?'
'You fool!' said the Master, 'You should fall into the nectar and submerge yourself!
When would you ever get this opportunity again?
Arjuna is on that verge of immersion. His intellect has almost disappeared. He needs the last nudge, so to speak.
You too, as the reader, make your plea to Parabrahma Kṛṣṇa, the Jagatguru, so that He may tell you about His glory, and so that you may meditate upon His glory with single pointed focus of the mind. As He promised, He will provide the light of wisdom for you to be enlightened.
