Having seen him thus, Hari, the lion-eyed, smiling between both armies, spoke to that one who was anguished among the sons of Dhṛtarāṣṭra

The moment of teaching. Hari (the yellow/golden one, name of Viṣṇu) is harya-kṣaḥ (lion-eyed) — majesty and contained ferocity. His response is prahasan (smiling) — not mockery but tenderness at his friend’s confusion.

The iva (as if, almost) modifies the smile: it is not open laughter but compassion that emerges. Samīkṣya (having examined) — Kṛṣṇa has completely observed before speaking.

The location is crucial: bhīṣma-droṇa-pramukhataḥ (at the front of Bhīṣma and Droṇa) — the teaching occurs in the most exposed space, visible to both armies. It is not intimate; it is public, paradoxical.
