Acosmism

The philosophy that denies the reality of the Universe, seeing it as ultimately illusory, and only the infinite Unmanifest Absolute as real. In contrast to pantheism, acosmism begins with the recognition that there is only one Reality, which is infinite, non-dual, blissful, etc. Yet the phenomenal reality of which humans are normally aware is none of these things; it is in fact just the opposite—i.e., dualistic, finite, full of suffering and pain, and so on. And since the Absolute is the only reality, that means that everything that is not Absolute cannot be real. Thus, according to this viewpoint, the phenomenal dualistic world is ultimately an illusion ("Maya" to use the technical Indian term), irrespective of the apparent reality it possesses at the mundane or empirical level.
