By its so-called advancement of knowledge, human civilization has created many material things, including spaceships and atomic energy. Yet it has failed to create a situation in which people need not die, take birth again, become old or suffer from disease. Whenever an intelligent man raises the question of these miseries before a so-called scientist, the scientist very cleverly replies that material science is progressing and that ultimately it will be possible to render man deathless, ageless and diseaseless. Such answers prove the scientists' gross ignorance of material nature. In material nature, everyone is under the stringent laws of matter and must pass through six stages of existence: birth, growth, maintenance, production of by-products, deterioration and finally death. No one in contact with material nature can be beyond these six laws of transformation; therefore no one-whether demigod, man, animal or plant-can survive forever in the material world.
The duration of life varies according to species. Lord Brahmā, the chief living being within this material universe, lives for millions and millions of years, while a minute germ lives for some hours only. But no one in the material world can survive eternally. Things are born or created under certain conditions, they stay for some time, and, if they continue to live, they grow, procreate, gradually dwindle and finally vanish. According to these laws, even the Brahmās, of which there are millions in different universes, are all liable to death either today or tomorrow. Therefore the entire material universe is called Martyaloka, the place of death.
Material scientists and politicians are trying to make this place deathless because they have no information of the deathless spiritual nature. This is due to their ignorance of the Vedic literature, which contains full knowledge confirmed by mature transcendental experience. Unfortunately, modern man is averse to receiving knowledge from the Vedas, Purāṇas and other scriptures.
