Just like Kṛṣṇa lifted the mountain, giri-bara-dhārī. Jaya rādhā-mādhava kuñja-bihārī gopī-jana-vallabha giri-bara-dhārī. When there was torrents of rain, Vṛndāvana was being overflooded, and all the inhabitants became so much disturbed. They were seeing to, looking to Kṛṣṇa, because they did not know anything beyond Kṛṣṇa. Kṛṣṇa said, "Yes, I am lifting this mountain. Let it become a big umbrella of the whole state, or whole village." The atheist will say these are all stories. No. They're not stories. Because God is supreme, He is supreme physist, He knows how to make this mountain weightless. He knows the art. Just like so many gigantic planets are floating in the sky. That is a fact. Now who is floating? You cannot float even a small thing in the air, but such gigantic... Not only one, millions and trillions, they are floating. Who has made it possible, floating? So, God can do that. Therefore He is called all-powerful, the great.
So if Kṛṣṇa is God, then floating or make this mountain weightless, is it very difficult task for Him? No. He entered the ocean. Unless He knows the physical laws how to enter the ocean... It is technique only. Modern scientists, they are also entering, by machine. They're floating by machine. That is also physical science. So, if you know the physical science still more perfectly, you can float in the air without machine, you can enter within the water without machine, you can lift the mountain without machine. It is a question of perfect knowledge.
