Arjuna calls Krishna by every name he knows — and still it is not enough. You are Vayu, the wind that carries breath. You are Yama, the final judge. You are Agni, the sacred fire. Varuna, lord of the waters. The Moon that lights the night. Prajapati, from whom all creatures descend. And beyond even Prajapati — the great-grandfather, the ancestor of the ancestors.
A thousand salutations. And again. And yet again. 'Namo namaste astu sahasrakritvah, punashcha bhuyopi namo namaste.' The repetition is not carelessness. It is the sound of a man whose language has run out. When you stand before something so vast that every description falls short, all that remains is to bow. And bow again. And again.
Every Vedic deity listed here governs a force of nature — wind, death, fire, water, moonlight, creation. By naming them all as aspects of Krishna, Arjuna is saying: every force I have ever encountered, every power I have ever prayed to, was You all along. There is no corner of existence where You are not.
