Vaiśampāyana said: “You are the ancient seer, of boundless spirit—Nara by name, mighty in strength. By Brahmā’s commission, dear one, you have entered the state of mortality. Arjuna, all of us guardians of the worlds have come here. Behold us. We grant you divine sight; you are worthy to receive our vision. You are the great-souled, great-powered primordial sage Nara. By Brahmā’s command you have assumed a human body.”

Educational Q&A

The verse frames Arjuna not merely as a warrior but as the primordial sage Nara who has taken on human mortality by Brahmā’s command. It emphasizes adhikāra (spiritual qualification): divine vision is granted when one is fit, and worldly identity can be a chosen role within a larger cosmic purpose.

The guardians of the worlds arrive and reveal themselves to Arjuna, granting him divine sight so he can behold them. They address him as the ancient sage Nara, explaining that he has assumed a human body due to Brahmā’s commission.
