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.
From the Viṣṇu Purāṇa (6.7.61, CC Madhya 6.154) we receive the following information:
- viṣṇu-śaktiḥ parā proktā
- kṣetra-jñākhyā tathā parā
- avidyā-karma-saṁjñānyā
- tṛtīyā śaktir iṣyate
Lord Viṣṇu, the Personality of Godhead, possesses different energies, known as parā (superior) and aparā (inferior). The living entities belong to the superior energy. The material energy, in which we are presently entangled, is the inferior energy. The material creation is made possible by this energy, which covers the living entities with ignorance (avidyā) and induces them to perform fruitive activities. Yet there is another part of the Lord's superior energy that is different from both this material, inferior energy and the living entities. That superior energy constitutes the eternal, deathless abode of the Lord.
