|Chapter 1: Observing the Armies on the Battlefield of Kurukshetra|
papam evasrayed asman
tasman narha vayam hantum
sva-janam hi katham hatva
sukhinah syama madhava
Sin will overcome us if we slay such aggressors. Therefore it is not proper for us to kill the sons of Dhritarashtra and our friends. What should we gain, O Krishna, husband of the goddess of fortune, and how could we be happy by killing our own kinsmen?
As per the Artha Sastra, six types of aggressors should be killed. At one point or other Kauravas had committed each of these acts. They had give poison (to Bhima in a cake), arson (burning of the house of lac in Varnavrata), theft (at the dice game where they won by cheating), occupying one's land (they had usurped the Pandavas) and kidnap of wife (Draupadi had been kidnapped by Jaydratha and earlier insulted in the Kuru assembly). Arjuna was aware of this but now he was talking from a higher platform, that of Dharma Sastra which says that it is not advisable to kill one's relatives and friends. So Arjuna because of his saintly qualities is prepared to forgive even those that deserve to die but in doing so he is neglecting that his own duty as a king is to fight irreligion in any form.
Srila Prabhupada comments, "Arjuna's addressing of Krishna as "Madhava," or the husband of the goddess of fortune, is also significant in this connection. He wanted to point out to Krishna that, as husband of the goddess of fortune, He should not induce Arjuna to take up a matter which would ultimately bring about misfortune. Krishna, however, never brings misfortune to anyone, to say nothing of His devotees."
