Now, suppose your father has got five sons. One of them is worthless, is doing nothing. And if the other son says: "My dear father, this son, your youngest son, or this son, is worthless. He is doing nothing. Let us kill him," will your father agree? Because he is worthless, will your father agree? No, he will say: "No, no, no. You have nothing to do. He is not harming you. He is eating my . . . my subsistence. I am paying for his subsistence. Why you should kill him?"
So similarly, in this material nature, all these living entities in different forms, they have come for material enjoyment, and everything is being supplied by the Supreme Lord. We have no right to kill them. We have no right. According to God's law, if one is conscious . . . the same thing. Just like the father will never agree to kill a worthless child by the competent boy. No.
So consciously or unconsciously, we are committing. Suppose I am not willingly killing any animal, but unconsciously I am killing so many living entities by my walking, by my so many things. They are called pañca-yajñas in the Vedic . . . so, and even if we do not kill animals, simply by eating vegetables, they are also life. It does not mean that vegetarians are not killing. They are also killing. The law is that a living entity lives by killing other living entity. That is the law. Those who have got hands, they are killing those who have got legs. Just like man is killing animal. The animal is eating the grass, those who have no legs. So this is the law.
But our thing is that we have to offer yajña. Killing of animal does not mean that if a man kills a cow or goat for eating, he is killing, and those who are vegetarian, they are not killing. They are also killing. A vegetable has also got life. So it is not the question of killing. It is the question of offering yajña. It is the question of offering yajña. Even animal eaters and flesh eaters, they have also some process for offering yajña. In the Vedic process, even the flesh eaters, they are also prescribed that "You can perform yajña like this." That yajña must be there. Yajña must be there.
But so far we are concerned who are going to have Kṛṣṇa consciousness, we have to take the instruction of Kṛṣṇa as He says in the Bhagavad-gītā. He says that patraṁ puṣpaṁ phalaṁ toyam (BG 9.26).
