Acosmism vs. Atheism — What's the Difference?

Acosmism, in contrast to pantheism, denies the reality of the universe, seeing it as ultimately illusory (the prefix "ἀ-" in Greek meaning negation; like "un-" in English), and only the infinite unmanifest Absolute as real. Conceptual versions of Acosmism are found in eastern and western philosophies.
