Prabhupada's lecture - Śrīmad-Bhāgavatam 1.8.34 - Bombay, October 14, 1974
In each of them... Gām āviśya [Bg. 15.13]. Dhārayāmy aham ojasā. Kṛṣṇa says in the Bhagavad-gītā that "I enter into each planetary system, each universe, and by My power I hold it. It is floating." Why it is floating? Because Kṛṣṇa is there. The atheist may not believe it, but it is a fact. It is a fact. How? Just like an animal or a man, while he is living, he can float in the air or in the water. That everyone has seen. But if the man is dead, it will not float. It will fall down. Is it not a fact? So why it is floating?
Because a very small particle of Kṛṣṇa's spiritual potency is there. That is living entity. Big, big... An elephant, he can also float in the water, and the horses, elephant, and what to speak of man? This is practical. Because a small particle of the Supreme is there within this body... Dehino 'smin yathā dehe [Bg. 2.13]. Very small particle. How much small? One ten-thousandth part of the top of the hair, so small. It has got so power that it can hold the whole body floating in the air. Air... There are very, very big, big birds. They are floating in the air, very, very big eagle. They fly from one planet to another. Their resting place is... They start from one planet, and they go and rest in other planet. And they lay their eggs while flying. That eggs also become a bird simply by air cohesion. That's all.
