Theosophical origin
The phrase Akashic Records appears to be a Theosophical coinage, drawing on Sanskrit ākāśa (the fifth element after earth, water, fire and air) but applying it as a metaphor for cosmic memory. Helena Blavatsky's The Secret Doctrine (1888) treats ākāśa as a substrate that retains every impression; Charles Leadbeater and Annie Besant systematised it as something a sufficiently trained clairvoyant could read.
Edgar Cayce
Cayce (1877-1945), the American sometimes called the Sleeping Prophet, gave roughly fourteen thousand trance readings over forty years, many of which involved diagnosing illness or describing past lives by reading what he called the Akashic Records. The Association for Research and Enlightenment in Virginia Beach holds the verbatim transcripts. His readings are evidentially complicated — some specific medical claims appear to have checked out, others did not — but they remain the largest single body of Akashic material in the English language.
In contemporary use
The phrase has now entered the loose vocabulary of popular esotericism, often without acknowledgement of its specifically Theosophical-Caycean genealogy. Hans Wilhelm refers to the records as the cosmic-memory substrate by which karma is stored across lifetimes; the framing recurs across channelled and clairvoyant traditions. As a metaphor for what mysticism has always claimed about cosmic memory, it is useful; as a literal claim about a queryable database, it asks for the kind of evidence the loose user rarely brings.
