The Akashic records (akasha is a Sanskrit word meaning “sky”, “space” or “aether”) is a term used in theosophy (and Anthroposophy) to describe a compendium of mystical knowledge encoded in a non-physical plane of existence. These records are described as containing all knowledge of human experience and the history of the cosmos. They are metaphorically described as a library; other analogies commonly found in discourse on the subject include a “universal supercomputer” and the “Mind of God”. People who describe the records assert that they are constantly updated automatically and that they can be accessed through astral projection or when someone is placed under deep hypnosis. The concept was popularized in the theosophical movements of the 19th century and is derived from Hindu philosophy of Samkhya. It is promulgated in the Samkhya philosophy that the Akashic records are automatically recorded in the atoms of akasha (the equivalent of what Aristotle called “aether”), one of the five types of atoms visualized as existing in the atomic theory of Ancient India, called Mahabhuta. In Buddhism it is taught one reason that people knew Gautama Buddha had attained enlightenment as a Buddha was because he was able to remember all of the details of all of his past lives by accessing them on the akashic records. The term akashic records is frequently used in New Age discourse.
