They do not know even that there is birth after death. Such a foolish civilization. Although we are experiencing every moment birth and death . . . Birth and death every moment, it is going on so finely. It is Kṛṣṇa's arrangement. Just like this world, this earthly planet, is moving at the rate of one thousand miles per hour. Such a gigantic body, it is also moving. Every, all planets are moving. Even the sun is moving. But we cannot perceive. You ride on a best airplane—there are so many disturbances: sound, moving, sometimes table is moving. But this planet also moving more speedily than the airplane, but you do not perceive. This is Kṛṣṇa's manufacture, perfectly. Pūrṇam idam. This is called pūrṇam idam, everything perfect. Pūrṇam idaṁ pūrṇam adaḥ pūrṇāt pūrṇam udacyate, pūrṇasya pūrṇam ādāya pūrṇam eva avaśiṣyate (Īśo Invocation). Because He is so perfect, we do not perceive. But it is moving.
Everyone knows that the morning there is sunrise, and in twelve hours, after covering twelve thousand miles, the evening is there. Again twelve thousand miles moving—you are sleeping—in the morning you see again the sun. The sun is there. Sun is not moving, but the world is moving. It is moving so nicely. Not only this earthly planet, but there are millions and trillions of planets within the sky. They are all moving. Seasonal changes, day and night, everything is going on. This is perfection. So those who are in divine nature, they can understand all these things. That is called daivī sampat.
