They say that this world is unreal, with no foundation, no God in control. They say it is produced of sex desire and has no cause other than lust.

16.8 They maintain that the universe is ‘without truth,’ viz., they do not accept that this universe, which is the effect of Brahman denoted by the term Satya, has Brahman for its Self. They contend that it is bereft of any ‘foundation,’ viz., they do not accept that it has Brahman for its foundation. Brahman as Ananta supports the earth and bears all the worlds, as declared in ‘This earth, sustained upon the head of this great serpent, supports in its turn, this garland of worlds, along with their men, demons and gods’ (V.P., 2.5.27). They say that it is ‘without a Lord,’ viz. they don’t accept that this universe is controlled by Me, the Lord of all, the Supreme Brahman, whose will is always true. It has been already averred: ‘I am the origin of all; from Me proceed everything’ (10.8). And they also contend thus: ‘What else can exist without mutual causation?’ i.e., except by the union of the male and the female among men, beasts etc. What else exists apart from this nature? The meaning is that nothing else is seen. Therefore the entire world is rooted in sexual lust.

16.8 Te, they, the domoniacal persons; ahuh, say; that the jagat, world; is asatyam, unreal-as we ourselves are prone to falsehood, so is this whole world unreal; apratistham, it has no basis, it does not have righteousness and unrighteousness as its basis; it is anisvaram, without a God-nor is there a God who rules this (world) according to rigtheousness and unrighteousness (of beings). Hence they say that the world is godless. Moreover, it is aparaspara-sambhutam, born of mutual union. The whole world is born of the union of the male and female impelled by passion. (That union is) kama-haitukam, brought about by passion. Kama-haitukam and kama-hetukam are the same. Kim anyat, what other (cause can there be)? There exists to other unseen cause such as righteousness, unrigtheousness, etc. Certainly, the passion of living beings is the cause of the world. This is the view of the materialists.

The material existence is real. This world is not an illusion. The incarnation Vedavyasa has written in Vedanta Sutra III.II.III beginning mayamatram tu kartsyena meaning: This world appears illusory because its nature is not manifest in its entirety. The Upanisads proclaim that the brahman or spiritual substratum pervading all existence has a twofold nature of manifest and unmanifest and this is the established form of the ultimate truth. All the worlds have been established by the Supreme Lord Krishna who has energised them and sustains them providing them the means to flourish and evolve. The Supreme Lord as isvaram parama the supreme controller who alone creates, maintains and destroys all existence yet the demoniac contrarily, adamantly oppose Him.
