Translation: "O my teacher, behold the great army of the sons of Pāṇḍu, so expertly arranged by your intelligent disciple, the son of Drupada."
Prabhupāda: So—intelligent. This Drupada, the son of Drupada, he was meant for killing Dronācārya. Drupada Mahārāja was not in good terms with Dronācārya. So he performed a yajña to get a son who could kill Dronācārya. That son is this Draupada. So Dronācārya knew that "Drupada Mahārāja has got his son. In future he would kill me." Still, when he was offered to become his disciple, to learn military art, he accepted, "Yes." That means the brāhmaṇas were so liberal: "When he is coming as my disciple, never mind, he would kill me in future. That doesn't matter. But I must give him teaching." Therefore this word is used, dhīmatā, very intelligent: "He has killed the military science from you just to kill you." Dhīmatā, tava śiṣyeṇa. "Your disciple, he has arranged." This is the pointing out. So that he may be angry: "This rascal has learned from me and he wants to kill me?"
