Instead of killing these high-souled Teachers, it is better to live here on alms. After killing the Teachers, whatever we enjoy in this world will be stained by their blood. We will also have abandoned dharma and moksha of the fourfold purusharthas, clinging only to artha and kama.
Arjuna’s zeal takes him to further important thoughts in the matter, which cannot be set aside easily: “In the impending war, Bheeshma and Drona have to be killed as part of the fighting mission. Rather than committing such a heinous crime, it is better to be a mendicant and go begging for livelihood.
“Moreover, should I fight and win the battle, that success will be stained with their blood. We would also be guilty of abandoning dharma and moksha of the four purusharthas (Fourfold pursuit of human life – dharma, artha, kāma and moksha).”
