Now the request comes. Arjuna says: "Everything you have described about yourself, O Parameshvara — I accept it fully. But I wish to see your majestic form, O Purushottama." The words carry a mix of trust and longing. He does not doubt Krishna's words. He simply wants to experience them firsthand.
There is a difference between being told that the ocean is vast and standing at its shore with water stretching to the horizon in every direction. Arjuna has heard the description. Now he wants the shore. He wants the salt air on his face, the roar in his ears.
Notice the two names Arjuna uses — Parameshvara (Supreme Lord) and Purushottama (Supreme Being). These are not casual. Arjuna is no longer speaking to his charioteer or even his friend. He is addressing the one he now recognizes as the source of all that exists.
