अर्जुन उवाच
कथं भीष्ममहं संख्ये द्रोणं च मधुसूदन ।
इषुभिः प्रतियोत्स्यामि पूजार्हावरिसूदन ।।
arjuna uvāca
kathaṃ bhīṣmamahaṃ saṃkhye droṇaṃ ca madhusūdana ।
iṣubhiḥ pratiyotsyāmi pūjārhāvarisūdana ।।
हत्वार्थकामांस्तु गुरूनिहैव भुञ्जीय भोगान् रुधिरप्रदिग्धान् ।।
gurūnahatvā hi mahānubhāvān śreyo bhoktuṃ bhaikṣyamapīha loke ।
hatvārthakāmāṃstu gurūnihaiva bhuñjīya bhogān rudhirapradigdhān ।।
Madhusudhana, my acharyas drona & bhisma are to be worshiped. How can I battle them with arrows?
Is it not better to beg for my living in this world without killing these acharyas of great repute?
Arjuna is implicitly addressing Krishna as arisudhana, madhusudhana. It means, even Krishna is only killing foes & not his acharyas (santIpini)
K - Arjuna, biksa (begging) is meant only for brahmanas. You are kshatriya. So even begging is a sin
A - Both are sins, but killing acharyas is a bigger sin & I would never do it
'dharmasya tatvam nihitam guhāyām | mahā jano yena gata: sa panthā ||'
If you don't kill them, then you will indirectly be responsible for killing of your own pandava brothers
