Why: having spoken thus, Krishna showed Arjuna his own, familiar form again, and comforted his terrified mind by becoming again the gentle, well-known figure, describing the actual, deliberate return to the more relatable form as its own act of care.

In life: deliberately returning to a more familiar, gentle way of relating after an intense moment is itself a real act of care, not merely a lesser or diminished version of the more intense encounter.

Teaching: after an intense, significant moment with someone, don't underestimate the value of deliberately returning to gentle, familiar ordinary interaction afterward, that return is itself part of the care, not a letdown from the intensity.
