I do not like to kill, but sometimes unintentionally they are killed. Therefore, according to Vedic literature, there are five kinds of yajña performed to get oneself free from this unintentional killing of animals. Now, here Kṛṣṇa says that śārīraṁ kevalaṁ karma kurvan nāpnoti kilbiṣam. If you make your principle of life that "I have to work simply for maintaining my body and soul together." Śārīram. Śarīram means body. Because I have to execute, I have to understand, Kṛṣṇa consciousness, but without this body, how can I understand or culture Kṛṣṇa consciousness? So my body must be maintained. And if I want to maintain my body, intentionally or unintentionally, I have to commit so many sins.
Take for example those who are vegetarians. They may think that "We are not killing animals." No. They are also committing sins because vegetables, they have also got life. So the nature's law is that to keep up your body you have to kill another body. Never mind it is vegetable or, I mean to say, animal or some fish or something else. You see? Jīvo jīvasya jīvanam: "One living entity is the subsistence, life-giving subsistence, for another living being." That is the nature's law. You'll find. Ahastāni sahastānām. The everything has been very nicely discussed in Vedic literature. They have discussed all the points.
Ahastāni sahastānām: "Those who have got hands, they are eating," I mean to say, "living entities who have no hands." That means we are human being, we have got hands, and we are eating animals. They have got only legs; they have no hands. So sahastānām ahastāni: "Those who have got hands, they are eating the animals which have no hands." And apadāni catuṣ-padām: "Those who have no legs, they are being eaten by the four-legged." Just like a cow eating grass. So grass cannot move. It has life, but it cannot move. So and... phalgūni tatra mahatām. Phalgūni, "those who are weak, they are being eaten by the..." Just like we find lizards. In your country you don't find lizards. In India we have got many lizards in the walls. They are eating small ants. Phalgūni mahatāṁ tatra. And in the snake, snake kingdom, you will find the small snakes are being by the big snake. Similarly, in sea water also, you will find small fishes are being eaten by the big fishes.
And the same law is applicable in human society. A big nation is trying to swallow up a small nation. You see? This is going on. This is nature's law. Nature's law. You cannot avoid it. But there are those who are Kṛṣṇa conscious. They... It is said that śārīraṁ kevalaṁ karma kurvan nāpnoti kilbiṣam: "Those who are in Kṛṣṇa consciousness, they are not entangled in these sinful acts." How? They are also maintaining their body. So when they are maintaining their body, they have to commit sins. They have to eat other animals or vegetables. Never mind. So how they are not committing sins? These are very intelligent questions. There is Kṛṣṇa consciousness.
A devotee of Lord Kṛṣṇa, he does not eat anything which is not offered to Kṛṣṇa. Just like you take the remnants of your master. Just like servant takes the remnants of master. The master eats. In India the process is that husband and wife, that after the husband eats, the remnants are taken by the wife. The wife does not eat along with the husband. That is the old system. Now it is being changed. The husband and wife, they do not... The husband is supplied by the wife all kinds of good dishes, and when the husband is satisfied, some foodstuff is left, and that is taken by the wife. So similarly, a devotee of Kṛṣṇa, he does not take anything, does not accept anything, which is not offered to Kṛṣṇa. This is the process. Because his life is full of Kṛṣṇa consciousness.
