Now, this soul, as in the previous verse we have understood, avināśi tu tad viddhi yena sarvam idaṁ tatam. This is not measurement of the soul, but the power of the soul you can measure. But not the soul. It is not possible. Soul is so small that it is not possible. You have no measuring means, and because now our material senses, it is not possible. You can simply understand by consciousness. Just like when Caitanya Mahāprabhu fainted in the Jagannātha temple, Sarvabhauma Bhaṭṭācārya examined that there was no consciousness. Even the abdomen was not moving. When you actually you have consciousness and you breathe, the abdomen moves. But Caitanya Mahāprabhu's abdomen was tested by Sarvabhauma Bhaṭṭācārya. It was also not moving. So he thought that "This sannyāsī might have died." But he again tried. He brought a little cotton swab and put before His nostril, and when he saw the swab, the fibers little moving, then he became hopeful, yes. So everything has got a different type of calculation, measurement. But so far the soul is concerned, it is said here, aprameyasya, there is no source of measurement. There is no source. Therefore, the so-called materialist science, they say there is no soul. No, there is soul. This is the proof there is soul. This is the proof. What is that proof? First of all there is consciousness. This is the proof. But you cannot measure. The place is also located. The soul is there in the heart. Īśvaraḥ sarva-bhūtānāṁ hṛd-deśe 'rjuna tiṣṭhati (BG 18.61).
So the soul is in the heart and Kṛṣṇa is also in the heart. Because they remain both together. So place is also located. You can perceive also by consciousness where there is presentation of soul, but if you want to measure by experiment, that is not possible. Therefore it is called aprameya. Prameya means direct perception. I can see or I can touch, I can handle. So that is... Kṛṣṇa says no, it is not possible. Aprameya. Then, how I shall accept? Now Kṛṣṇa says. So how I can believe Kṛṣṇa? Kṛṣṇa says ukta, it is already settled up by authorities. Ukta. This is paramparā system. Kṛṣṇa also says ukta. Kṛṣṇa does not say that "I speak," no. Ukta, there is Vedic evidence. Where it is? In the Upaniṣads there is. Just like,
- śatadhā kalpitasya ca
- bhāgo jīvaḥ sa vijñeyaḥ
- sa cānantyāya kalpate
It is in the Upaniṣad, Śvetāśvatara Upaniṣad. This is called Vedic evidence. In another, in the Śrīmad-Bhāgavatam, there is evidence. What is that? Keśāgra-śata-bhāgasya śatadhā, sadṛśaṁ jīvaḥ sūkṣma (CC Madhya 19.140). Sūkṣma, very fine. Jīvaḥ sūkṣma-svarūpo 'yaṁ saṅkhyātītaḥ kalpate. This jīva, not one, two, three, four—you cannot calculate. Asaṅkhya. So these are evidences in the Vedic literature. So we have to accept it. Kṛṣṇa confirms it and actually also you cannot measure. But we get evidence, the presence of the soul, presence of the soul. Still, how we can say there is no soul? No. This is foolishness. The whole world is going on under this foolishness. Not only now, before also. Like Cārvāka Muni, he was atheist, he did not believe. Lord Buddha also said like that, but He cheated. He knew everything because He is incarnation of God. But He had to cheat the people in that way because they are not intelligent enough. Why not intelligent? Because they were killers of animals, they lost their intelligence. Keśava dhṛta-buddha-śarīra jaya jagadīśa hare. Those who are animal killers, their brain is dull as stone. They cannot understand any thing. Therefore meat-eating should be stopped. In order to revive the finer tissues of the brain to understand subtle things, one must give up meat-eating.
