The Gita – Chapter 1 – Shloka 35

Shloka 35

हे मधुसूदन ! मुझे मारने पर भी अथवा तीनों लोकों के राज्य के लिये भी मैं इन सबको मारना नहीं चाहता, फिर पृथ्वी के लिये तो कहना ही क्या है ? ।। ३५ ।।

Arjuna spoke to the Lord Madhusudhana (Lord Krishna):
I could not slay (kill) my relatives even if I had to give my own life away. I could not slay them even for domination of the three worlds; how could I slay them for domination of this earth.
