Until now, Arjuna has been listing who is watching. Now he describes what they are watching. And the details are staggering: countless mouths, countless eyes, countless arms and legs, countless bellies — and rows of terrible fangs. This is not a gentle vision. This is the raw totality of existence staring back.
Arjuna does not hide behind bravery. He says it plainly: the worlds tremble, and I tremble with them. There is an honesty in this admission that is easy to miss. This is the greatest warrior of his age, the winner of divine weapons, the student of Drona and Indra. And he is shaking. Not from weakness — from the sheer, uncontainable enormity of what stands before him.
The word 'karalam' — terrible, fearsome — will echo through the coming shlokas. The Vishwarupa is not simply big. It is terrifying in the way that a storm at sea is terrifying: not because it means harm, but because it reveals how vast the forces of existence truly are.
