Arjuna puts his dilemma into words. How, he asks, can I fight against Bhishma and Drona in battle? How can I shoot arrows at men who deserve my reverence? Bhishma is his grandfather — the patriarch who raised the Kuru princes. Drona is his teacher — the man who placed the bow in his hands. The very arrows Arjuna would fire were, in a sense, gifts from Drona himself.
The word 'pujarhau' — worthy of worship — captures Arjuna's inner conflict. These are not enemies in his heart. They are elders he has bowed before since childhood. The idea of attacking them feels like a violation of something sacred, not a battlefield strategy.
Arjuna addresses Krishna by two names here: Madhusudana (slayer of the demon Madhu) and Arisudana (destroyer of enemies). Even as Arjuna speaks of his inability to fight, the names he chooses for Krishna carry the flavour of victory and strength — as if, somewhere beneath his grief, he knows the answer lies with Krishna.
