There is another side to this. The ‘divine eyes’ are not some cool sunglasses, but rather a change in perspective of the Lord.
No different from when we expect a Guru to perform miracles like levitation and telepathy, only to realize the real miracle was in his changing our minds!
It is easy to change anything in today’s world if you throw some money at it, but to really deeply change someone’s mind? Ask a parent about their adolescent kids. Or a husband/wife about their better half. “Impossible”, they will say.
And it’s not as though Lord Krishna had been hiding anything from Arjuna. He told him he was the Creator, Sustainer and Destroyer, and heck, even the substratum of all Creation!
But Arjuna didn’t really get it. It’s like meeting your childhood gully friend (the one you use to play with in all the dirt and dust, wearing only undies) after 3 decades only to realize he is now one of the richest people in the world. To you, that person is still the same old playmate from your childhood. Only when you see his face in a few magazines do you realize the truth.
And so he requests Krishna for a true-blue view.
