Here Arjuna speaks in the Gita for the first time. He turns to Krishna and says: "O Achyuta, drive my chariot to the middle ground between both armies. Let me see who has gathered here, eager to fight." It is the voice of a warrior sizing up the field before combat — calm, purposeful, direct.
Right now, there is no hesitation in Arjuna. He is thinking like a seasoned commander: first study the opponent, then form your strategy. It is like a captain surveying the other team before the match begins. But the sight waiting for him between those two armies will shake him in ways no enemy ever has.
The name "Achyuta" means one who never wavers, one who never falls from his position. Without knowing it, Arjuna is invoking exactly the quality he will soon need from Krishna — steadiness — because his own steadiness is about to collapse.
