Bhagavad Gita · Sankhya YogaChapter 2, Shloka 10 (2.10)

"Prahasann iva" — as if smiling. Before the grief-stricken Arjuna, Krishna smiles. Why?

• Shridhara: prasanna-mukhaḥ san — with a serene face. The simple meaning: Krishna is calm and serene.
• Madhusudana: "Prahasan" — exposing Arjuna's improper conduct, as if plunging him into an ocean of shame. But "iva" (as if) because the aim is not to shame him but to awaken discernment; Arjuna is worthy of the Lord's grace. Whether shame arises or not, that is not the aim.

"Senayor ubhayor madhye" — between the two armies. This phrase appeared in 1.21 and 1.24 — the very place where Arjuna saw his own people and broke down. Now, in that same place, Krishna gives knowledge. Many teachers take this as a symbol: knowledge was given not in some quiet ashram but right in the middle of the conflict. (This is an interpretation.)

The meaning of the smile. A teacher's smile before a sorrowing person is not an insult — it is a sign that the situation is not as hopeless as it looks. Like an experienced doctor smiling calmly at a frightened patient — because he knows the cure for the illness.

Madhusudana's hint about Dhritarashtra: Arjuna gave up the war, but the Lord did not give up Arjuna — by telling this, Sanjaya dispels Dhritarashtra's false hope.
