Purport. When an embodied living entity is hurt by fatal weapons, it is to be known that the living entity within the body is not killed. The spirit soul is so small that it is impossible to kill him by any material weapon, as will be evident from the subsequent verses. Nor is the living entity killable, on account of his spiritual constitution. What is killed or is supposed to be killed is the body only. This, however does not encourage killing of the body at all. The Vedic injunction is “ma himsyat sarva bhutani” never commit violence to anybody. To understand that a living entity is not killed does not mean encouraging animal slaughter. Even killing of the body of anyone without authority is abominable and punishable by the law of the state as well as by the law of the Lord. Arjuna, however, is being engaged in the matter of killing on principle of religion and not whimsically.
