Wiktionary
a. Not manifest.
Wikipedia
The unmanifested is the Absolute, the pure and formless ground of being from which creation and manifestation arise. As such, the unmanifested is free from change, the unmoved mover. It also, necessarily, cannot be explained or comprehended in terms of any manifest reality.
Some schools of belief hold that the manifest and unmanifested are part of the same reality (e.g. pantheism), others believe that the Absolute is the only reality with all manifestation being illusory (e.g. acosmism), a third belief posits that the one God interpenetrates every part of nature, and timelessly extends beyond as well (e.g. panentheism).
