The camera pulls back. Sanjaya, narrating from the Kuru court for the blind king Dhritarashtra, describes the scene. Having spoken those reassuring words, Vasudeva showed Arjuna His own familiar form once again. The great soul assumed a gentle appearance and comforted His terrified friend.
Sanjaya's narration here does something the dialogue alone cannot. It gives us the view from outside. We have been inside the storm — hearing Krishna's thunder, feeling Arjuna's fear. Now Sanjaya shows us the aftermath: a calm figure, a gentle face, a friend putting his hand on another friend's shoulder.
The word 'saumyavapuh' (gentle-bodied) lands with quiet force after dozens of shlokas describing blazing mouths, infinite arms, and world-swallowing fire. Like sunlight after a storm, the return to the familiar form carries its own kind of power.
