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 is the Sanskrit word for "aether", "sky", or "atmosphere".

Theosophical Society
The Sanskrit term akasha was introduced to the language of theosophy through Helena Blavatsky, who characterized it as a sort of life force; she also referred to "indestructible tablets of the astral light" recording both the past and future of human thought and action, but she did not use the term "akashic". The notion of an akashic record was further disseminated by Alfred Percy Sinnett in his book Esoteric Buddhism when he cites Henry Steel Olcott's A Buddhist Catechism. Olcott wrote that "Buddha taught two things are eternal, viz, 'Akasa' and 'Nirvana': everything has come out of Akasa in obedience to a law of motion inherent in it, and, passes away. No thing ever comes out of nothing."By C. W. Leadbeater's Clairvoyance the association of the term with the idea was complete, and he identified the akashic records by name as something a clairvoyant could read.
In his 1913 book, Man: Whence, How and Whither, Leadbeater claims to record the history of Atlantis and other civilizations as well as the future society of Earth in the 28th century.
