Akashic records
Rudolf Steiner and Edgar Cayce claimed access to the Akashic records
In the religion of Theosophy and the spiritual movement of Anthroposophy, the Akashic records are believed to be a compendium of all universal events, thoughts, words, emotions, and intent ever to have occurred in the past, present, or future, regarding not just humans, but all entities and life forms. They are believed by theosophists to be encoded in a non-physical plane of existence known as the mental plane.
Akasha (ākāśa आकाश) is the Sanskrit word for "aether", "sky", or "atmosphere".
