एतान्न हन्तुमिच्छामि घ्नतोऽपि मधुसूदन। अपि त्रैलोक्यराज्यस्य हेतोः किं नु महीकृते
etān na hantum ichchhāmi ghnato ’pi madhusūdana api trailokya-rājyasya hetoḥ kiṁ nu mahī-kṛite
I would not kill them, even for three worlds; why then for this earth alone? It matters not if I myself am killed.
Translated by Shri Purohit Swami
These I do not wish to kill, O Krishna, even though they kill me, for the sake of dominion over the three worlds; leave alone killing them for the sake of the earth."
Translated by Swami Sivananda
