Bhagavad Gita · Arjuna Vishada YogaChapter 1, Shloka 7 (1.7)

"Tu" — but. Madhusudana Sarasvati makes a profound point. If Drona were thinking, "if you are so afraid of the enemy, why not make a sandhi (settlement)?", Duryodhana turns with the word "tu" to cut that thought off. In Madhusudana's words — with the word "tu" he conceals the fear that has arisen within and displays his dhrishtata (stubborn bravado).

"Dvijottama" — two meanings. Drona was a brahmana by birth, and a master of the science of arms. Duryodhana calls him "dvijottama" (best of the brahmanas). Madhusudana gives two readings of this single word:

1. As praise: flattering the teacher to win him over to his purpose.
2. The barbed (ironic) reading: "you are a brahmana after all — not all that skilled in war anyway; even if you don't put your heart into it, we have the finest kshatriyas like Bhishma, so we won't lose much."

Both readings are possible in the word. After the taunt of "tava shishyena dheemata" in the earlier shloka (1.3), the second reading does not seem out of place either.

"Saṃjñārtham" — for your information. Did Drona not know the commanders of his own army? Of course he did. So why is Duryodhana counting off names? Here too Madhusudana says two things: (1) by naming a few of the countless warriors, he points to the rest — "I'm not telling you anything new"; and (2) a stinging remark — "seeing the army of your beloved disciples (the Pandavas), you have become so happy that you might forget your own heroes — so I am reminding you."

His manner of speaking: Every sentence of Duryodhana's carries two layers — respect on top, pressure underneath. This is the language of a person sunk in anxiety who cannot admit his anxiety.
