Translation:

O respected preceptor, look at the huge and vast army of Pandava’s , it is arranged by your favorite student son of Drupad.

Meaning:

Guru Dronacharya and King Drupad had some political differences and Duryodhana knew this very well, He wanted to ignite the fire within Dronacharya by remembering him that Drishtadhumna is not just student of Dronacharya but he is son of King Drupad. It is said that Drishtadhumna was born to kill Dronacharya. Drishtadhumna had been sent to Guru Dronacharya for learning war skills, and even though Dronacharya knew the fact, He taught Drishtadhumna every skill and art of war.

Drushatadhumna was supporting Pandava’s and he arranged the military phalanx. Dronacharya was feeling proud for his student, and seeing this Duryodhana reminded him that Dronacharya was Kaurava’s supporter.

Well, we all are in same boat. I feel the moral of the verse is, we should be faithful and loyal to our work. May be Dronacarya knew at one point that Drishtadhumna was born to kill him, but he was loyal to his work and he taught him all skills, he gave best of his knowledge to his enemy King Drupad’s son. He feels proud for his student when he looked at the arrangement in Pandava’s military phalanx. He was least bothered about the happenings.

Same like Guru Dronacharya we all should always try to keep loyalty and always be faithful to our work come what may. It is said Loyalty pays, provided you should be in right team like pandava’s. Guruji had chosen to support Kaurava’s and he was loyal to them as well.

Gitaji is just not a religious book, it teaches us the values , which makes us different from other animals. It has been narrated over 2000 years but it teaches us  applied science, art of living , and many more..it is encyclopedia for generations and it will be applied in every age.. :)

Think over it .. :)
