पश्यैतां पाण्डुपुत्राणामाचार्य महतीं चमूम्।व्यूढां द्रुपदपुत्रेण तव शिष्येण धीमता॥
paśyaitāṃ pāṇḍu-putrāṇām ācārya mahatīṃ camūmvyūḍhāṃ drupada-putreṇa tava śiṣyeṇa dhīmatā
Word by word
The verse says
Look, teacher, at this great army of the sons of Pandu, drawn up by your own gifted student, the son of Drupada.
In plain words
This sounds like a briefing. It is a needle.
The man who arranged the Pandava army is Dhrishtadyumna, and Drona trained him personally. Worse, Dhrishtadyumna was born for one purpose, which everybody standing there knows: to kill Drona. His father had him brought into the world for exactly that.
So Duryodhana's opening line to his commander is, in effect, look what your own student built, and remember what he was born to do to you. He calls it respect. It is pressure.
Where you've felt this · at work
A manager opens a meeting by warmly praising a colleague for how well he trained the person who just left for a rival firm. Everyone hears the compliment. Everyone hears the other thing too. Nobody can object, because on the surface nothing rude was said.
Going deeper
This verse is worth slowing down on, because it shows what kind of man started this war.
Duryodhana is not stupid and not weak. He is doing something quite precise: making his best general uneasy, minutes before a battle, to keep him sharp and loyal. It is the technique of someone who has learned to manage people through their soft places.
Notice too that it is a teacher he is doing it to. The Gita has a great deal to say about teachers - Krishna becomes one in the next chapter, and Arjuna will formally ask to be taught. Here at the start we get the opposite picture: a student using what he knows about his teacher as a lever.
The two relationships sit on either side of the same book. One man uses his teacher. The other surrenders to his. Only the second one changes.
