You have to depend on God, on the mercy of God. What is this rainfall? This rainfall is an arrangement, taking water from the seas and spread all over the surface of the land. But you cannot do it. The seawater you can spread by pumping or by some other means, but that will not serve your purpose. The seawater must be distilled. It must be made into sweetness. Then such rainfall will give you some effect in producing agricultural production and so many. So every way we are dependent on the Supreme Personality of Godhead.
When we speak of Kṛṣṇa, we mean the Supreme Personality of Godhead. So here, Kṛṣṇa is teaching Himself, God is teaching, Himself, what is God, what is the science of God. You cannot speculate on the science of God, "God may be like this. God may be like that." No. You have to know God from God Himself. Just like you cannot speculate about the position of a very big man. Suppose there is a very big man in your country.
If you speculate about him at home, the knowledge is never perfect. It cannot be. Speculative knowledge is never perfect, especially when you imagine something about somebody. That is all humbug; it has no meaning. So God cannot be realized by speculation. But here is a chance wherein God is speaking about Himself, so you can understand what is God. Now in this verse, Bhagavad-gītā, Kṛṣṇa says:
- mayy āsakta-manaḥ pārtha
- yogaṁ yuñjan mad-āśrayaḥ
- asaṁśayaṁ samagraṁ māṁ
- yathā jñāsyasi tac chṛṇu
- (BG 7.1)
