Parīkṣit Mahārāja. He said that God consciousness, Kṛṣṇa consciousness, cannot be understood by the animal killer. Vinā paśughnāt (SB 10.1.4). Nivṛtta-tarṣair upagīyamānāt. You'll find those who are animal killers, the so-called Christians and Mohammedans, they cannot understand. They (are) simply fanatics. Cannot understand what is soul, what is God. They have got some theories and they are thinking we are religionists. What is sin, what is pious activities, these things are not understood by them because they are animal killers. It is not possible. Therefore Lord Buddha propagated ahiṁsā. Ahiṁsā. Because he saw the whole human race is going to hell by this animal killing. "Let me stop them so that they may, in future, they may become sober." Sadaya-hṛdaya darśita: Two sides. First of all he was very much compassionate, that poor animals, they are being killed. And another side, he saw "The whole human race is going to hell. So let me do something." Therefore he had to deny the existence of the soul because their brain will not tolerate such things. Therefore he did not say anything about the soul or God. He said that "You stop animal killing." If I pinch you, you feel pain. So why should you give pain to others? Never mind he has no soul; that's all right. He did not talk anything about soul. So these people say the animals have no soul. But that's all right, but he's feeling pain when you are killing the animal. So you also feel pain. So why should you give pain to others? That is Lord Buddha's theory. Sadaya-hṛdaya darśita-paśu-ghātam. Nindasi yajña-vidher ahaha śruti-jātam. He denied that: "I don't accept Vedas." Because in the Vedas there is sometimes recommendation, not for killing, but for giving rejuvenation to an animal. But killing, in that sense, is there for sacrifice. But Lord Buddha did not accept even animal killing in sacrifice. Therefore, nindasi. Nindasi means he was criticizing. Nindasi yajña-vidher ahaha śruti-jātaṁ sadaya-hṛdaya darśita. Why? He was so kind and compassionate. That is Kṛṣṇa consciousness. God is very kind, very compassionate. He does not like. But when there is necessity, He can kill. But His killing and our killing is different. He's all good. Anyone killed by Kṛṣṇa, he immediately gets salvation. So these thing are there.
So, immeasurable. You cannot measure what is the soul, but the soul is there, and the body is perishable. "If you, even if you do not fight, you save the bodies of your grandfather and teacher and others as you are so much overwhelmed, so they are perishable. Antavanta means today or tomorrow. Suppose your grandfather is already old. So you do not kill him just now or, say, after one year or six months, he may die because he's already old. These are the arguments put forward. The main point is Kṛṣṇa wants Arjuna that he must fight. He must, he must not deviate from his duty as a kṣatriya. He should not be overwhelmed by the bodily destruction. Therefore He is giving instruction: "The body is different from the soul. So don't think that the soul will be killed. You stand up and fight." This is the instruction.
