The gross materialists, however, do not believe in the anti-material worlds of the Personality of Godhead. They are therefore unfortunate creatures, although sometimes very talented, educated and advanced otherwise. They are bewildered by the influence of the material manifestation and are devoid of knowledge of things anti-material. It is a good sign, therefore, that the materialistic scientists are gradually progressing toward the region of the anti-material world. It may even be possible for them to make sufficient progress to be able to know the details of this anti-material world, where the Personality of Godhead resides as the predominating figure and where the living entities live with Him and serve Him. The living entities who serve the Godhead are equal in quality to Him, but at the same time they are predominated as servitors. In the anti-material world there is no difference between the predominated and the predominator—the relationship is in perfection and without tinge of materialism.
The nature of the material world is destructive. According to the Bhagavad-gītā, there is some partial truth to the assumption of the physical scientist that there is annihilation of the material and anti-material worlds when they chance to clash. The material world is a creation of changing modes of nature. These modes (guṇas) are known as sattva (goodness), rajas (passion) and tamas (ignorance). The material world is created by the mode of rajas, maintained by the mode of sattva, and annihilated by the mode of tamas. These modes are omnipresent in the material world, and as such, at every hour, every minute, every second, the process of creation, maintenance and annihilation is taking place all over the material universe. The highest planet of the material universe, Brahmaloka, is also subjected to these modes of nature, although the duration of life on that planet, due to the predominance of the mode of sattva, is said to be 4,300,000 x 1,000 x 2 x 30 x 12 x 100 solar years. Despite this long duration, however, Brahmaloka is subject to destruction. Although life on Brahmaloka is fantastically long compared to life on Earth, it is only a flash in comparison to the eternal life of the nonmaterial worlds. Consequently, the speaker of the Bhagavad-gītā, Lord Śrī Kṛṣṇa, asserts the importance of the anti-material universe, which is His abode.
