The vision sharpens around specific details. Arjuna sees a crown, a mace, a discus — the iconic attributes of Vishnu. But these familiar symbols are set ablaze. The entire form is a mass of radiance, shining in every direction, blazing with the combined brilliance of fire and sun. And Arjuna admits: it is hard to look at. Even with divine sight, the intensity is almost unbearable.
There is something striking about this admission. Krishna gave Arjuna divine eyes specifically to see this form. And still, Arjuna finds it 'durniriksyam' — difficult to behold. It is as if the divine sight opened a door, but what lay beyond the door was so vast and bright that even enhanced eyes strained under the weight of it.
The word 'aprameyam' — immeasurable, beyond proof — closes the verse. Arjuna is saying: I cannot measure this. I cannot contain it in concepts. I can only stand here and look, and even looking is difficult.
