The akashic records – akasha being a Sanskrit word meaning "sky", "space" or "aether" – are described as containing all knowledge of human experience and all experiences as well as the history of the cosmos encoded or written in the very aether or fabric of all existence. The records or The Book of Life in the Bible (Psalm 69:28, Philippians 4:3, Revelation 3:5, 13:8, 17:8, 20:12, 20:15 and Revelation 21:27) are described as being in a non-physical plane described as a library; other analogies commonly found in discourse on the subject include a "universal supercomputer" and the "Mind of God".
