अस्माकं तु विशिष्टा ये तान्निबोध द्विजोत्तम।नायका मम सैन्यस्य संज्ञार्थं तान्ब्रवीमि ते॥
asmākaṃ tu viśiṣṭā ye tānnibodha dwijottamanāyakā mama sainyasya sanjñārthaṃ tānbravīmi te
Word by word
The verse says
But know too, best of the twice-born, who among us stands out - the leaders of my army. Let me name them for you.
In plain words
Duryodhana turns at last to his own side. Notice what he needs before he can do it.
He addresses Drona with a title of honour and then says, essentially, now let me tell you about us. He has to announce the change of subject. He needs a run-up.
And there is the small word mama - my army. Not ours.
Where you've felt this · in community
Four neighbours are rebuilding a shared wall. For two weeks it is "our wall". Then one Saturday only one of them turns up, and by evening he is calling it "my wall". Nothing was announced. He started carrying it alone, and the word changed with him.
Going deeper
One word is worth catching here, because it echoes the opening line of the whole book.
Dhritarashtra began by splitting the field into my men and the sons of Pandu. His son now does the same thing to his own army - mama, mine. It is a family habit of speech, and this family's habit of speech is the reason there is a war at all.
The Gita spends much of its length on that one word. Mine is the root of the ownership Krishna names again and again as the thing that ties a person down. In Chapter 12 he describes the people closest to him by its opposite - nirmama, without-mine. Not people who own nothing. People who have stopped stamping mine on whatever passes through their hands.
The first chapter shows you the problem at work in ordinary speech, long before anybody gives it a name. Once you know to listen for it, you will hear it in your own sentences.
