Try to understand how Kṛṣṇa . . . because we have got very limited knowledge. Ātmavat manyate jagat. The same Dr. Frog. Dr. Frog is calculating in his own way, and he is puzzled how there can be an Atlantic Ocean or Pacific Ocean. Because he has never experienced, he has no idea, he is thinking, "This three feet water expansion, that is very big water."
So our folly is that we are trying to study Kṛṣṇa, or God, by our own standard, frog standard. We do not know how great Kṛṣṇa is, how His potency is great, how He is manufacturing, how He is . . . because we think, "If we have to manufacture something, I require some tools, I require some energy, I require some ingredients. I have to collect it. Then I can make."
Therefore we are surprised, "How Kṛṣṇa can make, or how God can create, this universe? Where is that instrument? Where is that ingredient?" They cannot. They are thinking in that way that, "I require instrument; Kṛṣṇa requires the hammer and the saw to manufacture this comic manifestation." I am thinking in that way.
Therefore I cannot believe it, how the cause of this cosmic manifestation can be a person. They are thinking imperson. Impersonal bigness, they think it is very important. Actually, it has no value. Background is person. Kṛṣṇa says in the Bhagavad-gītā that brahmaṇo 'haṁ pratiṣṭha (BG 14.27):
"The impersonal Brahman, I am the cause. I am the source of impersonal Brahman."
So these things cannot be understood by ordinary brain. It requires a different brain. That brain is created by devotional service, these finer tissues. Just like those who are dull materialists, their brain is congested with so much rubbish thing, they cannot understand that it is through the bodily effulgence of the Lord the potential manifestation is this cosmic manifestation. They will think that like Dr. Frog: "If it is created by God, where He got so much ingredient, so much instrument, that He created?" Yes.
But God's creation is not like that. Automatically the effulgence is coming. Just like the sun . . . from the sun disc, automatically the heat is profusely distributed and everything is taking place out of His own . . . the sun-god, or the sun, or the predominating deity in the sun planet, he does not come out to manufacture another planet. He is there.
You can understand from this material example how things are being created through the sunlight, how the planets are growing due to sunlight. If there is no sunlight, we'll see all plants will die. That is our experience. And because the sunlight is there, the plant is growing, they are becoming green, they are becoming red, they are becoming flavored.
So all interaction of these five elements, water, earth, fire, heat and ether . . . so where from the sunlight comes? From the sun. Wherefrom the sun comes? From the brahma-jyotir. Wherefrom the brahma-jyotir comes? It is from Kṛṣṇa. Try to understand how Kṛṣṇa is the Absolute Truth, or the original source of everything. Mattaḥ sarvaṁ pravartate, ahaṁ sarvasya prabhavaḥ (BG 10.8)
"I am the origin. I am the source of all creation," Bhagavad-gītā says: "and from Me everything is coming."
