पश्यैतां पाण्डुपुत्राणामाचार्य महतीं चमूम्।
व्यूढां द्रुपदपुत्रेण तव शिष्येण धीमता।।1.3।।
।।1.3।।हे आचार्य आपके बुद्धिमान् शिष्य द्रुपदपुत्र धृष्टद्युम्नके द्वारा व्यूहरचनासे खड़ी की हुई पाण्डवोंकी इस बड़ी भारी सेनाको देखिये।
These very words, O respected preceptor, please behold are understood to introduce this theme up until verse twelve. O respected preceptor, please behold the Pandava army consisting of seven aksauhinis arrayed and displayed in battle formation by Dhrishtadyumna, the son of Draupada.
Madhvacarya has no commentary so we present Baladeva Vidyabhusanas. Duryodhana is thinking that Drona might decline to fight in the battle, out of affection for the Pandavas who had been his best disciples. So trying to create some anger in Drona towards them, Duryodhana sneered and exclaimed pasyaitam: Behold these! Implying that the Pandavas are despicable because they are blatantly disrespecting the acarya by choosing to fight against their own preceptor. Then to incite Drona further Duryodhana says that the military formation of the Pandava army has been arrayed by another one of his disciples, the intelligent son of Drupada. Duryodhana could have called the son of Drupada by his name Dhristadyumna; but he purposely used drupada-putra because it would remind Drona of his bitter enemy, King Drupada, who performed a sacrifice specifically to get a son who would be the slayer of Drona. This son was Dhristayumna. Duryodhana is calling Dristadyumna intelligent because he had learned the science of warfare from the very person he was born to kill. Futhermore Duryodhana is implying that it was imprudent of Drona to teach the science of archery to the very person who was destined to kill him and who was known to be his enemy. Duryodhanas intention in expressing these things is that it is because of Dronas indifference to things he was aware of and in educating the enemy anyway will be the cause of all the problems they will face in the battle.
There is no commentary for this verse.
Duryodhana in order to kindle some anger in the heart of his preceptor Drona, speaks about the excellence of the Pandava army cynically using the words: Behold the mighty army of the Pandavas well arranged in military phalanx. Here Duryodhana is conveying to Drona that the Pandavas have come prepared to engage in battle. Duryodhana wants to further incite Drona against the Pandavas by the use of the word Behold implying that with unmitigated arrogance the Pandavas are fast approaching without waiting for us to start who are depending upon Drona himself. If Drona then puts forth that the Pandavas are his pupils as well and due to Yudhisthira being elder have the right to start before you if they so desire. But Duryodhana anticipating that response, overtly mentions Dhritadyumna the commander of the Pandava army by calling him the son of Drupada, to remind Drona of his being the son of his mortal enemy, so there should be no compassion for them. If Drona then argues that one should not fight with the son of an enemy who is commander of an opposing army, Duryodhana by also referring to Dhritadyumna as Dronas disciple neutralises that argument by the offence incurred of his in choosing to fight against a preceptor a condemned action so there is no doubt as to motivation. Duryodhana by also calling Dhristadyumna intelligent suggests that everything as a pupil he learned from Drona would now be used against him so there should be no hesitation or neglect towards him as he has made up his mind to take Dronas life. What Sanjaya is subtlety conveying to Dhritarastra is that his son, King Duryodhana uninfluenced by the sanctity Kuruksetra possesses no inclination for righteousness. A serpent even though fed with milk does give up its venom; on the contrary it increases its poison and anger. So also the same regarding your son, you should not worry that he will ever return to the kingdom to the Pandavas for he definitely will not.
