We understand from the śāstras that Kṛṣṇa, as Garbhodakaśāyī Viṣṇu, He created water within this universe and lied down, Garbhodakaśāyī Viṣṇu. Now, we cannot conceive that how a person can produce water from the body like the sea and ocean. But if you think over little soberly, that sometimes we perspire, we get perspiration, that is water. In India, we have got special experience during summer season: sometimes a small pot can be filled up with the water produced from my body like this, put. Of course, one must be healthy man; then he'll perspire and water will come out from the body. So I am limited. I am only a small particle of Kṛṣṇa's body, part and parcel. If I have got this power of producing water, maybe one grain or two grain or one ounce, Kṛṣṇa has got unlimited power—why not a sea? Where is the difficulty to understand? He can produce unlimited quantity of water, which may be known as ocean and sea. Yato vā imāni bhūtāni jāyante (Taittirīya Upaniṣad 3.1).
Therefore Vedas say that, "From whom all these five elements have come into being?" And Kṛṣṇa says:
- bhūmir āpo 'nalo vāyuḥ
- khaṁ mano buddhir eva ca
- ahaṅkāra itīyaṁ me
- bhinnā prakṛtir aṣṭadhā
- (BG 7.4)
"That is my energy." So everything is Kṛṣṇa's energy. He can produce. Try to verify from the example. Because you are little sample of Kṛṣṇa. You can study what you are doing, what you are feeling, what you are acting. The same thing in unlimited quantity, Kṛṣṇa has got the power. That's all.
So here it is said, Arjuna might be thinking that, "Kṛṣṇa says this body is different from the soul. The soul is within. So now suppose when I place my sword on the body of my grandfather or my kinsmen, the body will cut, and in the meantime, the soul is within the body, it may be cut, because the soul is there. By accidentally, he may be cut."
