The akashic recors (akasha is a Sanskrit word meaning "sky", "space" or "aether") is a term from Hinduism that was incorporated into theosophy describing a compendium of mystical knowledge encoded in a non-physical plane of existence. These records are described to contain all knowledge of human experience and the history of the cosmos. They are metaphorically described as a library and other analogues commonly found in discourse on the subject include a 'universal computer' and the 'Mind of God'. Descriptions of the records assert that they are constantly updated and that they can be accessed through astral projection. The concept originated in the theosophical movements of the 19th Century, and remains prevalent in New Age discourse.
