Just like if you kill a . . . some animal with your stick, the stick is not responsible; you are responsible. Similarly, if I become a stick and instrument in the hands of Kṛṣṇa, then I am not responsible for any karma. Otherwise, I am responsible.
Just like a soldier, his business is killing by the order of the state. He's killing so many persons, and he's getting recognition, medal, gold medal. And as soon as he comes home, if he kills one person, he'll be hanged. He can say: "My dear sir, I killed so many persons in the battlefield. I was awarded gold medal. Now I have killed only one person. Why you are hanging me?" Because you have done for your own sense gratification. And so many soldiers, it mean, men, you kill in the battlefield, that was the order of the state.
This is same position. Yajñārthe means to act on the order of the Supreme. That is called yajña. Anything which you act for satisfaction of the Supreme, that is called yajña. Yajñārthe karmaṇo 'nyatra. Just like in the Viṣṇu Purāṇa it is said:
- varṇāśramācāravatā
- puruṣeṇa paraḥ pumān
- viṣṇur ārādhyate pumsam
- nānyat tat-toṣa-kāraṇam
- (CC Madhya 8.58)
