द्रोणं च भीष्मं च जयद्रथं च
कर्णं तथान्यानपि योधवीरान् |
मया हतांस्त्वं जहि मा व्यथिष्ठा
युध्यस्व जेतासि रणे सपत्नान् ||११-३४||
droṇaṃ ca bhīṣmaṃ ca jayadrathaṃ ca karṇaṃ tathānyānapi yodhavīrān .
mayā hatāṃstvaṃ jahi mavyathiṣṭhā yudhyasva jetāsi raṇe sapatnān ||11-34||
In plain words
Already slain by Me Therefore. O Arjuna you need not be afraid of incurring sin by killing them. Drona had celestial weapons.
Translation
11.34 Slay Drona, Bhisma, Jayadratha, Karna as well as other mighty warriors, who have been doomed by Me. Do not feel distressed. Fight, You shall coner your rivals in the battle.
Meaning
Already slain by Me Therefore. O Arjuna you need not be afraid of incurring sin by killing them. Drona had celestial weapons. He was Arjunas teacher in the science of archery. He was Arjunas beloved and greatest Guru. Bhishma also possessed celetial weapons. He could die only if and when he wanted to die. He once faught singlehanded with Lord Parasurama and was not defeated. So powerful was he. The father of Jayadratha performed penance with a resolve the head of the man who may cause the head of my son to fall on the ground shall also fall. During the war however. Arjunas arrow cuts the head and drops it on the lap of the father who inadvertently makes it fall on the ground he too dies at once. Karna the son of the Sungod had obtained an unerring missile from Indra.
